Vulnerabilities

With the aim of informing, warning and helping professionals with the latest security vulnerabilities in technology systems, we have made a database available for users interested in this information, which is in Spanish and includes all of the latest documented and recognised vulnerabilities.

This repository, with over 75,000 registers, is based on the information from the NVD (National Vulnerability Database) – by virtue of a partnership agreement – through which INCIBE translates the included information into Spanish.

On occasions this list will show vulnerabilities that have still not been translated, as they are added while the INCIBE team is still carrying out the translation process. The CVE  (Common Vulnerabilities and Exposures) Standard for Information Security Vulnerability Names is used with the aim to support the exchange of information between different tools and databases.

All vulnerabilities collected are linked to different information sources, as well as available patches or solutions provided by manufacturers and developers. It is possible to carry out advanced searches, as there is the option to select different criteria to narrow down the results, some examples being vulnerability types, manufacturers and impact levels, among others.

Through RSS feeds or Newsletters we can be informed daily about the latest vulnerabilities added to the repository. Below there is a list, updated daily, where you can discover the latest vulnerabilities.

CVE-2024-39562

Publication date:
10/07/2024
A Missing Release of Resource after Effective Lifetime vulnerability the xinetd process, responsible for spawning SSH daemon (sshd) instances, of Juniper Networks Junos OS Evolved allows an unauthenticated network-based attacker to cause a Denial of Service (DoS) by blocking SSH access for legitimate users. Continued receipt of these connections will create a sustained Denial of Service (DoS) condition.<br /> <br /> The issue is triggered when a high rate of concurrent SSH requests are received and terminated in a specific way, causing xinetd to crash, and leaving defunct sshd processes. Successful exploitation of this vulnerability blocks both SSH access as well as services which rely upon SSH, such as SFTP, and Netconf over SSH.<br /> <br /> Once the system is in this state, legitimate users will be unable to SSH to the device until service is manually restored.  See WORKAROUND section below.<br /> <br /> Administrators can monitor an increase in defunct sshd processes by utilizing the CLI command:<br /> <br />   &gt; show system processes | match sshd<br />   root   25219 30901 0 Jul16 ?       00:00:00 [sshd] <br /> <br /> This issue affects Juniper Networks Junos OS Evolved:<br /> * All versions prior to 21.4R3-S7-EVO<br /> * 22.3-EVO versions prior to 22.3R2-S2-EVO, 22.3R3-S2-EVO;<br /> * 22.4-EVO versions prior to 22.4R3-EVO;<br /> * 23.2-EVO versions prior to 23.2R2-EVO.<br /> <br /> <br /> <br /> This issue does not affect Juniper Networks Junos OS Evolved 22.1-EVO nor 22.2-EVO.
