Airlive · Airlive Bu-3026 · CVE-2015-2279
**Name of the Vulnerable Software and Affected Versions**
AirLive BU-2015 version 1.03.18
AirLive BU-3026 version 1.43
AirLive MD-3025 version 1.81
**Description**
The issue allows remote attackers to execute arbitrary OS commands via shell metacharacters after an "&" (ampersand) in the `write mac`, `write pid`, `write msn`, `write tan`, or `write hdv` parameter. This is due to the lack of measures to neutralize special elements used in the operating system command. Exploitation of the issue may allow a remote attacker to execute arbitrary OS commands using shell metacharacters.
**Recommendations**
For AirLive BU-2015 version 1.03.18, consider disabling the `cgi test.cgi` script until a patch is available.
For AirLive BU-3026 version 1.43, restrict access to the `write mac`, `write pid`, `write msn`, `write tan`, and `write hdv` parameters in the `cgi test.cgi` script to minimize the risk of exploitation.
For AirLive MD-3025 version 1.81, avoid using the `write mac`, `write pid`, `write msn`, `write tan`, and `write hdv` parameters in the `cgi test.cgi` script until the issue is resolved.
At the moment, there is no information about a newer version that contains a fix for this issue.
