CVE-2024-6387, dubbed the regreSSHion vulnerability, is a critical Remote Code Execution (RCE) flaw found in the OpenSSH server on glibc-based Linux systems, identified by the Qualys Threat Research Unit. This vulnerability arises from a signal handler race condition in the OpenSSH server, potentially allowing unauthenticated remote attackers to execute code as root, posing a significant security threat. Despite its severity, exploiting this vulnerability is challenging due to its race-condition nature, requiring numerous attempts for successful exploitation, and no effective exploits have been reported thus far. The vulnerability impacts certain versions of OpenSSH, excluding OpenBSD systems, which preemptively implemented a secure mechanism to prevent such issues. Mitigation strategies include patch management, access control, and network segmentation, while detection can be achieved by analyzing sshd logs for suspicious activities using Dynatrace's DQL queries. Although the vulnerability is difficult to exploit, organizations are advised to assess and mitigate potential risks to secure their systems adequately.
