Brandon Rothel from QED Secure Solutions has found that the VAPIX API tcptest.cgi did not have a sufficient input validation allowing for a possible remote code execution. This flaw can only be exploited after authenticating with an operator- or administrator-privileged service account. The impact of exploiting this vulnerability is lower with operator-privileges compared to administrator-privileges service accounts. Axis has released patched AXIS OS versions for the highlighted flaw. Please refer to the Axis security advisory for more information and solution.
