An Uncontrolled Resource Consumption vulnerability in the http daemon (httpd) of Juniper Networks Junos OS on SRX Series, QFX Series, MX Series and EX Series allows an unauthenticated, network-based attacker to cause Denial-of-Service (DoS).<br /> <br /> An attacker can send specific HTTPS connection requests to the device, triggering the creation of processes that are not properly terminated. Over time, this leads to resource exhaustion, ultimately causing the device to crash and restart.<br /> <br /> The following command can be used to monitor the resource usage:<br /> user@host&gt; show system processes extensive | match mgd | count<br /> <br /> This issue affects Junos OS on SRX Series and EX Series:<br /> All versions before 21.4R3-S7,<br /> from 22.2 before 22.2R3-S4,<br /> from 22.3 before 22.3R3-S3,<br /> from 22.4 before 22.4R3-S2,<br /> from 23.2 before 23.2R2-S1,<br /> from 23.4 before 23.4R1-S2, 23.4R2.

A NULL Pointer Dereference vulnerability in the Packet Forwarding Engine (pfe) of Juniper Networks Junos OS allows a local, low-privileged attacker to cause a Denial-of-Service (DoS).<br /> <br /> When a specific command is executed, the pfe crashes. This will cause traffic forwarding to be interrupted until the system self-recovers. Repeated execution will create a sustained DoS condition.<br /> <br /> This issue only affects MX Series devices with Line cards MPC1-MPC9.<br /> This issue affects:<br /> Junos OS on MX Series: <br /> <br /> <br /> * All versions before 21.4R3-S9, <br /> * from 22.2 before 22.2R3-S5, <br /> * from 22.3 before 22.3R3-S4, <br /> * from 22.4 before 22.4R3-S2, <br /> * from 23.2 before 23.2R2-S1, <br /> * from 23.4 before 23.4R2.

An Unimplemented or Unsupported Feature in UI vulnerability in the CLI of Juniper Networks Junos OS Evolved on QFX5000 Series allows an unauthenticated, adjacent attacker to cause a Denial-of-Service (DoS).<br /> <br /> Several configuration statements meant to enforce limits on MAC learning and moves can be configured but do not take effect. This can lead to control plane overload situations which will severely impact the ability of the device to processes legitimate traffic.<br /> <br /> <br /> <br /> This issue affects Junos OS Evolved on QFX5000 Series:<br /> <br /> <br /> <br /> * All versions before 21.4R3-S8-EVO,<br /> * 22.2-EVO versions before 22.2R3-S5-EVO,<br /> <br /> * 22.4-EVO versions before 22.4R3-EVO,<br /> * 23.2-EVO versions before 23.2R2-EVO.

An Improper Check for Unusual or Exceptional Conditions vulnerability in the routing protocol daemon (RPD) of Juniper Networks Junos OS and Junos OS Evolved allows an unauthenticated, network based attacker to cause a Denial of Service (DoS). <br /> <br /> In a scenario where BGP Monitoring Protocol (BMP) is configured with rib-in pre-policy monitoring, receiving a BGP update with a specifically malformed AS PATH attribute over an established BGP session, can cause an RPD crash and restart.<br /> <br /> This issue affects:<br /> <br /> Junos OS: <br /> <br /> <br /> <br /> * All versions before 21.2R3-S8,<br /> * 21.4 versions before 21.4R3-S8,<br /> * 22.2 versions before 22.2R3-S4,<br /> * 22.3 versions before 22.3R3-S3,<br /> * 22.4 versions before 22.4R3-S2,<br /> * 23.2 versions before 23.2R2-S1,<br /> * 23.4 versions before 23.4R1-S2, 23.4R2;<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> Junos OS Evolved:<br /> <br /> <br /> <br /> <br /> * All versions before 21.2R3-S8-EVO,<br /> * 21.4 versions before 21.4R3-S8-EVO,<br /> * 22.2 versions before 22.2R3-S4-EVO,<br /> * 22.3 versions before 22.3R3-S3-EVO,<br /> * 22.4 versions before 22.4R3-S2-EVO,<br /> * 23.2 versions before 23.2R2-S1-EVO,<br /> * 23.4 versions before 23.4R1-S2-EVO, 23.4R2-EVO.

An Authorization Bypass Through User-Controlled Key vulnerability allows a locally authenticated attacker with shell access to gain full control of the device when Dual Routing Engines (REs) are in use on Juniper Networks Junos OS Evolved devices.<br /> <br /> This issue affects:<br /> Juniper Networks Junos OS Evolved with dual-REs:<br /> * All versions before 21.2R3-S8-EVO,<br /> * from 21.4-EVO before 21.4R3-S8-EVO,<br /> * from 22.2-EVO before 22.2R3-S4-EVO,<br /> * from 22.3-EVO before 22.3R3-S4-EVO,<br /> * from 22.4-EVO before 22.4R3-S3-EVO,<br /> * from 23.2-EVO before 23.2R2-S1-EVO,<br /> * from 23.4-EVO before 23.4R2-S1-EVO.<br /> <br /> <br /> <br /> This issue does not affect Juniper Networks Junos OS.

A Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in the AgentD process of Juniper Networks Junos OS allows an attacker who is already causing impact to established sessions which generates counter changes picked up by the AgentD process during telemetry polling, to move the AgentD process into a state where AgentD attempts to reap an already destroyed sensor. This reaping attempt then leads to memory corruption causing the FPC to crash which is a Denial of Service (DoS).<br /> <br /> <br /> <br /> <br /> <br /> The FPC will recover automatically without user intervention after the crash.<br /> This issue affects Junos OS: <br /> <br /> * All versions before 21.4R3-S9<br /> * From 22.2 before 22.2R3-S5,<br /> * From 22.3 before 22.3R3-S4,<br /> * From 22.4 before 22.4R3-S3,<br /> * From 23.2 before 23.2R2-S2,<br /> * From 23.4 before 23.4R2.<br /> <br /> <br /> This issue does not affect Junos OS Evolved.

A Missing Release of Memory after Effective Lifetime vulnerability in the Packet Forwarding Engine (PFE) of the Juniper Networks Junos OS on the MX Series platforms with Trio-based FPCs allows an unauthenticated, adjacent attacker to cause a Denial of Service (DoS).<br /> <br /> In case of channelized Modular Interface Cards (MICs), every physical interface flap operation will leak heap memory. Over a period of time, continuous physical interface flap operations causes local FPC to eventually run out of memory and crash.  <br /> <br /> Below CLI command can be used to check the memory usage over a period of time:<br /> <br />   user@host&gt; show chassis fpc<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br />                 Temp CPU Utilization (%)   CPU Utilization (%) Memory   <br /> Utilization (%)<br />   Slot State     (C)  Total  Interrupt     1min   5min  <br /> 15min DRAM (MB) Heap     Buffer<br /> <br />   0 <br /> Online       43     41         <br /> 2                           2048       49         14<br /> <br />   1 <br /> Online       43     41         <br /> 2                          <br /> 2048       49         14<br /> <br />   2 <br /> Online       43     41         <br /> 2                          <br /> 2048       49         14<br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> <br /> This issue affects Junos OS on MX Series: <br /> <br /> <br /> <br /> <br /> * All versions before 21.2R3-S7, <br /> * from 21.4 before 21.4R3-S6, <br /> * from 22.1 before 22.1R3-S5, <br /> * from 22.2 before 22.2R3-S3, <br /> * from 22.3 before 22.3R3-S2, <br /> * from 22.4 before 22.4R3, <br /> * from 23.2 before 23.2R2, <br /> * from 23.4 before 23.4R2.

An Improper Handling of Exceptional Conditions vulnerability in the Routing Protocol Daemon (rpd) of Juniper Networks Junos OS and Junos OS Evolved allows a network-based, unauthenticated attacker to cause Denial of Service (DoS).<br /> <br /> When a BGP UPDATE with malformed path attribute is received over an established BGP session, rpd crashes and restarts. <br /> <br /> Continuous receipt of a BGP UPDATE with a specifically malformed path attribute will create a sustained Denial of Service (DoS) condition for impacted devices. While this issue affects systems running 32-bit and 64-bit systems, the probability of impact on 64-bit system is extremely low. <br /> According to KB25803 https://supportportal.juniper.net/s/article/Junos-How-to-check-if-Junos-OS-is-64-or-32-bit-on-a-router , customers can confirm 32-bit or 64-bit system via the &amp;#39; show version detail &amp;#39; command:<br /> <br /> <br /> <br />      lab@router&gt; show version detail| match 32<br />      JUNOS 32-bit kernel Software Suite <br /> <br />      lab@router&gt; show version detail| match 64<br />      JUNOS 64-bit kernel Software Suite <br /> <br /> <br /> This issue affects:<br /> <br />  Juniper Networks Junos OS: <br /> <br /> * All versions before 21.4R3-S8, <br /> * from 22.2 before 22.2R3-S4, <br /> * from 22.4 before 22.4R3-S3, <br /> * from 23.2 before 23.2R2-S1, <br /> * from 23.4 before 23.4R1-S2, 23.4R2.<br /> <br /> <br />  Juniper Networks Junos OS Evolved:  * All versions before 21.4R3-S8-EVO, <br /> * from 22.2 before 22.2R3-S4-EVO, <br /> * from 22.4 before 22.4R3-S3-EVO,<br /> * from 23.2 before 23.2R2-S1-EVO, <br /> * from 23.4 before 23.4R1-S2-EVO, 23.4R2-EVO.

An Improper Restriction of Communication Channel to Intended Endpoints vulnerability in the Packet Forwarding Engine (PFE) of Juniper Networks Junos OS Evolved on ACX 7000 Series allows an unauthenticated, network based attacker to cause increased consumption of resources, ultimately resulting in a Denial of Service (DoS).<br /> <br /> When specific transit MPLS packets are received by the PFE, these packets are internally forwarded to the Routing Engine (RE), rather than being handled appropriately. Continuous receipt of these MPLS packets causes resources to be exhausted. MPLS config is not required to be affected by this issue. <br /> <br /> <br /> This issue affects Junos OS Evolved ACX 7000 Series: <br /> <br /> <br /> <br /> * All versions before 21.4R3-S9-EVO,<br /> * 22.2-EVO before 22.2R3-S4-EVO, <br /> * 22.3-EVO before 22.3R3-S3-EVO, <br /> * 22.4-EVO before 22.4R3-S2-EVO, <br /> * 23.2-EVO before 23.2R2-EVO, <br /> * 23.4-EVO before 23.4R1-S1-EVO, 23.4R2-EVO.

An Improper Handling of Exceptional Conditions vulnerability in the Packet Forwarding Engine (pfe) of the Juniper Networks Junos OS Evolved on ACX Series devices allows an unauthenticated, network based attacker sending specific transit protocol traffic to cause a partial Denial of Service (DoS) to downstream devices.<br /> <br /> Receipt of specific transit protocol packets is incorrectly processed by the Routing Engine (RE), filling up the DDoS protection queue which is shared between routing protocols. This influx of transit protocol packets causes DDoS protection violations, resulting in protocol flaps which can affect connectivity to networking devices.<br /> <br /> This issue affects both IPv4 and IPv6. This issue does not require any specific routing protocol to be configured or enabled.<br /> <br /> The following commands can be used to monitor the DDoS protection queue:<br /> <br />        labuser@re0&gt; show evo-pfemand host pkt-stats<br /> <br />     labuser@re0&gt; show host-path ddos all-policers<br /> <br /> This issue affects Junos OS Evolved: <br /> <br /> <br /> <br /> * All versions before 21.4R3-S8-EVO, <br /> * from 22.2 before 22.2R3-S4-EVO, <br /> * from 22.3 before 22.3R3-S4-EVO, <br /> * from 22.4 before 22.4R3-S3-EVO, <br /> * from 23.2 before 23.2R2-EVO, <br /> * from 23.4 before 23.4R1-S1-EVO, 23.4R2-EVO, <br /> * from 24.2 before 24.2R2-EVO.

angular-base64-upload prior to v0.1.21 is vulnerable to unauthenticated remote code execution via demo/server.php. Exploiting this vulnerability allows an attacker to upload arbitrary content to the server, which can subsequently be accessed through demo/uploads. This leads to the execution of previously uploaded content and enables the attacker to achieve code execution on the server. NOTE: This vulnerability only affects products that are no longer supported by the maintainer.
