Sandro Poppi, member of the AXIS OS Bug Bounty Program, has found that the VAPIX API overlay_del.cgi is vulnerable to path traversal attacks that allows for file deletion. This flaw can only be exploited after authenticating with an operator- or administrator-privileged service account. Axis has released patched AXIS OS versions for the highlighted flaw. Please refer to the Axis security advisory for more information and solution.
