We have discovered security vulnerabilities which affect both RT 4.0.x and RT 4.2.x. We are releasing RT versions 4.0.24 and 4.2.12 to resolve these vulnerabilities, as well as patches which apply atop all released versions of 4.0 and 4.2.
The vulnerabilities addressed by 4.0.24, 4.2.12, and the below patches include the following: RT 4.0.0 and above are vulnerable to a cross-site scripting (XSS) attack via the user and group rights management pages. This vulnerability is assigned CVE-2015-5475. It was discovered and reported by Marcin Kopeć at Data Reliance Shared Service Center. RT 4.2.0 and above are vulnerable to a cross-site scripting (XSS) attack via the cryptography interface. This vulnerability could allow an attacker with a carefully-crafted key to inject JavaScript into RT's user interface. Installations which use neither GnuPG nor S/MIME are unaffected. Patches for all releases of 4.0.x and 4.2.x are available for download below. Versions of RT older than 4.0.0 are unsupported and do not receive security patches; please contact sa...@bestpractical.com if you need assistance with an older RT version. https://download.bestpractical.com/pub/rt/release/security-2015-08-12.tar.gz https://download.bestpractical.com/pub/rt/release/security-2015-08-12.tar.gz.asc 0ffdfae09837c09957f69e9de69660735d3099ee security-2015-08-12.tar.gz 92c8d4d299c7bc205eb8382274306dc3aaa14970 security-2015-08-12.tar.gz.asc The README in the tarball contains instructions for applying the patches.
