Vulnerabilities

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.

An Incorrect Default Permissions vulnerability in the command line interface (CLI) of Juniper Networks Junos OS Evolved allows a low privileged local attacker to view NETCONF traceoptions files, representing an exposure of sensitive information.<br /> <br /> <br /> <br /> On all Junos OS Evolved platforms, when NETCONF traceoptions are configured, NETCONF traceoptions files get created with an incorrect group permission, which allows <br /> <br /> a low-privileged user can access sensitive information compromising the confidentiality of the system.<br /> <br /> <br /> <br /> Junos OS Evolved: <br /> <br /> <br /> <br /> <br /> * All versions before 20.4R3-S9-EVO, <br /> * 21.2-EVO before 21.2R3-S7-EVO, <br /> * 21.4-EVO before 21.4R3-S5-EVO, <br /> * 22.1-EVO before 22.1R3-S5-EVO, <br /> * 22.2-EVO before 22.2R3-S3-EVO, <br /> * 22.3-EVO before 22.3R3-EVO, 22.3R3-S2-EVO, <br /> * 22.4-EVO before 22.4R3-EVO, <br /> * 23.2-EVO before 23.2R1-S2-EVO, 23.2R2-EVO.

A Command Injection vulnerability in Juniper Networks Junos Space allows an unauthenticated, network-based attacker sending a specially crafted request to execute arbitrary shell commands on the Junos Space Appliance, leading to remote command execution by the web application, gaining complete control of the device.<br /> <br /> A specific script in the Junos Space web application allows attacker-controlled input from a GET request without sufficient input sanitization. A specially crafted request can exploit this vulnerability to execute arbitrary shell commands on the Junos Space Appliance.<br /> <br /> This issue affects Junos Space 24.1R1. Previous versions of Junos Space are unaffected by this vulnerability.

An Improper Handling of Exceptional Conditions vulnerability in the rpd-server of Juniper Networks Junos OS and Junos OS Evolved within cRPD allows an unauthenticated network-based attacker sending crafted TCP traffic to the routing engine (RE) to cause a CPU-based Denial of Service (DoS).<br /> <br /> If specially crafted TCP traffic is received by the control plane, or a TCP session terminates unexpectedly, it will cause increased control plane CPU utilization by the rpd-server process.<br /> <br /> While not explicitly required, the impact is more severe when RIB sharding is enabled.<br /> <br /> Task accounting shows unexpected reads by the RPD Server jobs for shards:<br /> <br /> user@junos&gt; show task accounting detail<br /> ...<br /> read:RPD Server.0.0.0.0+780.192.168.0.78+48886 TOT:00000003.00379787 MAX:00000000.00080516 RUNS: 233888\<br /> read:RPD Server.0.0.0.0+780.192.168.0.78+49144 TOT:00000004.00007565 MAX:00000000.00080360 RUNS: 233888\<br /> read:RPD Server.0.0.0.0+780.192.168.0.78+49694 TOT:00000003.00600584 MAX:00000000.00080463 RUNS: 233888\<br /> read:RPD Server.0.0.0.0+780.192.168.0.78+50246 TOT:00000004.00346998 MAX:00000000.00080338 RUNS: 233888\<br /> <br /> <br /> <br /> This issue affects:<br /> <br /> Junos OS with cRPD: <br /> <br /> * All versions before 21.2R3-S8, <br /> * 21.4 before 21.4R3-S7, <br /> * 22.1 before 22.1R3-S6, <br /> * 22.2 before 22.2R3-S4, <br /> * 22.3 before 22.3R3-S3, <br /> * 22.4 before 22.4R3-S2, <br /> * 23.2 before 23.2R2-S2, <br /> * 24.2 before 24.2R2; <br /> <br /> <br /> Junos OS Evolved with cRPD: <br /> <br /> * All versions before 21.4R3-S7-EVO, <br /> * 22.2 before 22.2R3-S4-EVO, <br /> * 22.3 before 22.3R3-S3-EVO, <br /> * 22.4 before 22.4R3-S2-EVO, <br /> * 23.2 before 23.2R2-EVO.

A DLL hijack vulnerability was reported in Lenovo Service Framework that could allow a local attacker to execute code with elevated privileges.

An Incorrect Comparison vulnerability in the local address verification API of Juniper Networks Junos OS Evolved allows an unauthenticated network-adjacent attacker to create sessions or send traffic to the device using the network and broadcast address of the subnet assigned to an interface. This is unintended and unexpected behavior and can allow an attacker to bypass certain compensating controls, such as stateless firewall filters.<br /> <br /> This issue affects Junos OS Evolved: <br /> <br /> <br /> <br /> * All versions before 21.4R3-S8-EVO, <br /> * 22.2-EVO before 22.2R3-S4-EVO, <br /> * 22.3-EVO before 22.3R3-S4-EVO, <br /> * 22.4-EVO before 22.4R3-S3-EVO, <br /> * 23.2-EVO before 23.2R2-S1-EVO, <br /> * 23.4-EVO before 23.4R1-S2-EVO, 23.4R2-EVO.

An Exposure of Sensitive Information to an Unauthorized Actor vulnerability in the command-line interface (CLI) of Juniper Networks Junos OS on SRX Series devices allows a local, low-privileged user with access to the Junos CLI to view the contents of protected files on the file system.<br /> <br /> Through the execution of crafted CLI commands, a user with limited permissions (e.g., a low privilege login class user) can access protected files that should not be accessible to the user. These files may contain sensitive information that can be used to cause further impact to the system.<br /> <br /> This issue affects Junos OS on SRX Series: <br /> <br /> <br /> <br /> * All versions before 21.4R3-S8, <br /> * 22.2 before 22.2R3-S5, <br /> * 22.3 before 22.3R3-S4, <br /> * 22.4 before 22.4R3-S4, <br /> * 23.2 before 23.2R2-S2, <br /> * 23.4 before 23.4R2.

An Improper Handling of Exceptional Conditions vulnerability in packet processing of Juniper Networks Junos OS on MX Series with MPC10/MPC11/LC9600 line cards, EX9200 with EX9200-15C lines cards, MX304 devices, and Juniper Networks Junos OS Evolved on PTX Series, allows an attacker sending malformed DHCP packets to cause ingress packet processing to stop, leading to a Denial of Service (DoS).  Continued receipt and processing of these packets will create a sustained Denial of Service (DoS) condition.<br /> <br /> This issue only occurs if DHCP snooping is enabled. See configuration below.<br /> <br /> This issue can be detected using following commands. Their output will display the interface status going down:<br /> <br /> <br /> user@device&gt;show interfaces <br /> user@device&gt;show log messages | match <br /> user@device&gt;show log messages ==&gt; will display the "[Error] Wedge-Detect : Host Loopback Wedge Detected: PFE: no," logs.<br /> <br /> This issue affects:<br /> Junos OS on <br /> <br /> MX Series <br /> <br /> with MPC10/MPC11/LC9600 line cards, EX9200 with EX9200-15C line cards, and MX304: <br /> <br /> <br /> * All versions before 21.2R3-S7, <br /> * from 21.4 before 21.4R3-S6, <br /> * from 22.2 before 22.2R3-S3, <br /> * all versions of 22.3,<br /> * from 22.4 before 22.4R3, <br /> * from 23.2 before 23.2R2; <br /> <br /> <br /> <br /> Junos OS Evolved on PTX Series: <br /> * from 19.3R1-EVO before 21.2R3-S8-EVO,<br /> <br /> * from 21.4-EVO before 21.4R3-S7-EVO, <br /> * from 22.1-EVO before 22.1R3-S6-EVO, <br /> * from 22.2-EVO before 22.2R3-S5-EVO, <br /> * from 22.3-EVO before 22.3R3-S3-EVO, <br /> * from 22.4-EVO before 22.4R3-S1-EVO, <br /> * from 23.2-EVO before 23.2R2-S2-EVO, <br /> * from 23.4-EVO before 23.4R2-EVO.<br /> <br /> <br /> <br /> Junos OS Evolved releases prior to 19.3R1-EVO are unaffected by this vulnerability
