**Name of the Vulnerable Software and Affected Versions** FSMLabs TimeKeeper version 8.0.17 **Description** A cross-site scripting (XSS) issue was found, allowing for the injection of JavaScript code on specific screens. The affected screens include "Configuration -> Compliance -> Add a new compliance report" and "Configuration -> Timekeeper Configuration -> Add a new source there". **Recommendations** For FSMLabs TimeKeeper version 8.0.17, as a temporary workaround, consider restricting access to the "Configuration -> Compliance -> Add a new compliance report" and "Configuration -> Timekeeper Configuration -> Add a new source there" screens until a patch is available. At the moment, there is no information about a newer version that contains a fix for this issue.

**Name of the Vulnerable Software and Affected Versions** FSMLabs TimeKeeper versions 8.0.17 through 8.0.28 **Description** The issue is related to insufficient input validation in the FSMLabs TimeKeeper software. It allows an attacker to intercept requests from various timekeeper streams and find the getsamplebacklog call. The attacker can modify the `arg[2]` query parameter to insert Bash code, which will be executed directly by the server. This can enable a remote attacker to execute arbitrary code. **Recommendations** For FSMLabs TimeKeeper versions 8.0.17 through 8.0.28, consider restricting access to the getsamplebacklog call and validating all input parameters, especially `arg[2]`, to prevent code injection. As a temporary workaround, consider disabling the execution of Bash code from the `arg[2]` parameter until a patch is available.
