CVE-2019-17571 is a critical vulnerability affecting Log4j, a widely used logging library. This vulnerability, specifically related to the SocketServer class in Log4j 1.2, allows for the deserialization of untrusted data. When exploited, it can lead to remote code execution, potentially compromising the security of affected systems.
How do I know if I'm affected?
To determine if you're affected by the vulnerability, check if you're using Log4j versions up to 1.2.17. This vulnerability has been found in various systems, including openSUSE, NetApp products, and Ubuntu 18.04 ESM. If you're using OnCommand System Manager 3.x, OnCommand Workflow Automation, or have not updated your Log4j package in Ubuntu 18.04, you may be affected. Keep in mind that this vulnerability allows for remote code execution through the deserialization of untrusted data in the SocketServer class of Log4j.
What should I do if I'm affected?
If you're affected by the vulnerability, it's important to update your system to mitigate the risk. For openSUSE Leap 15.1, use the command zypper in -t patch openSUSE-2020-51=1. For Ubuntu 18.04, update to liblog4j1.2-java 1.2.17-8+deb10u1build0.18.04.1. For Debian, upgrade your apache-log4j1.2 packages to the fixed versions mentioned in the advisory. Always keep your software up-to-date to maintain security.
Is this in CISA’s Known Exploited Vulnerabilities Catalog?
The CVE-2019-17571 vulnerability is not listed in CISA's Known Exploited Vulnerabilities Catalog. This Log4j vulnerability allows attackers to remotely execute arbitrary code by sending specially crafted log data. To mitigate the risk, it's important to update your system to the recommended package versions and follow the recommendations provided in the available resources.
Weakness enumeration
The weakness enumeration for this vulnerability is categorized as CWE-502, which is related to the deserialization of untrusted data in Log4j's SocketServer class, which can lead to remote code execution. Affected versions are up to 1.2.17.
