CVSS v2.0

6.8

Medium

Base vector

AV:N/AC:M/Au:N/C:P/I:P/A:P

Name of the Vulnerable Software and Affected Versions SysAid Help Desk versions prior to 15.2

Description The issue is related to the RdsLogsEntry servlet, which does not properly check file extensions. This allows remote attackers to upload and execute arbitrary files by appending a NULL byte after the extension. For example, uploading a file with a .war%00 extension can lead to the execution of the file.

Recommendations For versions prior to 15.2, update to version 15.2 or later to resolve the issue. As a temporary workaround, consider restricting file uploads to only trusted sources and validating file extensions to prevent malicious uploads.
