CVE-2019-25741: MobaXterm 12.1 has a SEH buffer overflow in session files, allowing unauthenticated remote code execution.

Vulnerability

Mobatek MobaXterm version 12.1 contains a Structured Exception Handling (SEH) based buffer overflow vulnerability within the username field of session files. This vulnerability is present in versions up to and including 12.1 [1].

Exploitation

An attacker can craft a malicious MobaXterm session file containing overflow data. This malicious file, when imported and executed by a victim, triggers the vulnerability. No specific network position, authentication, or user interaction is required beyond the victim importing the crafted session file [1].

Impact

Successful exploitation allows remote attackers to execute arbitrary code. This can lead to a reverse shell execution with the privileges of the user running MobaXterm, potentially compromising the user's system [1].

Mitigation

Mobatek MobaXterm versions up to and including 12.1 are affected. A fixed version has not yet been disclosed in the available references. Users are advised to exercise caution when importing session files from untrusted sources [1].
