FreeBSD : element-web -- Cross site scripting in Export Chat feature (c70c3dc3-258c-11ee-b37b-901b0e9408dc)

medium Nessus Plugin ID 178441

Language:

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the c70c3dc3-258c-11ee-b37b-901b0e9408dc advisory.

 - Since the Export Chat feature generates a separate document, an attacker can only inject code run from the null origin, restricting the impact. However, the attacker can still potentially use the XSS to leak message contents. A malicious homeserver is a potential attacker since the affected inputs are controllable server-side. (CVE-2023-37259)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
