Title: FireGPG PGP Key Issuer Name HTML Injection Vulnerability
Severity: MODERATE
Description:
FireGPG is a Firefox extension that allows users to sign, verify, encrypt, and decrypt text using GnuGPG.
FireGPG is prone to an HTML-injection vulnerability because it fails to sufficiently sanitize user-supplied input. This issue affects the PGP Key Issuer contained in the public key block of a PGP key.
Attacker-supplied HTML or JavaScript code could run in the context of the website that the application is triggered from, potentially allowing an attacker to steal cookie-based authentication credentials and to control how the site is rendered to the user; other attacks are also possible.
This issue affects FireGPG 0.4.6; prior versions may also be affected.
Affected Products:
- FireGPG FireGPG 0.4.6
