Executive brief
GFI Archiver, a solution used for archiving corporate emails and files, contains a security flaw in its retention policy settings. An authorized user can inject malicious code into a policy name, which will then run in the browsers of other administrators who view the policy page. This could allow an attacker to perform unauthorized actions or steal session information from other users of the management console.
Technical details
A stored cross-site scripting (XSS) vulnerability exists in GFI Archiver versions prior to 15.13. The flaw is located in the Retention Policy configuration wizard, specifically within the 'policy name' parameter handled by /Archiver/RetentionPolicyWizard.aspx. The application's SaveAllConfigSettings() function fails to perform proper output encoding before storing the input. An authenticated attacker with network access to the management interface can inject a malicious payload that executes in the context of any user who subsequently views the Retention and Spam Policies page. This issue was addressed in version 15.13.
