Cross-site Scripting in Mahara 1.4.0 and 1.3.6
03 November 2011, 17:48
| Category: | Cross-site Scripting |
| Severity: | High |
| Versions affected: | < 1.3.7, < 1.4.1 |
| Reported by: | Teemu Vesala |
| Identifier: | CVE-2011-2771 |
| Bug report: | 798136 |
The externalfeed block did not sanitize certain URLs contained in RSS feeds and this could therefore be used as a cross-site scripting vector.
We strongly recommend that all Mahara administrators upgrade to the latest version if the externalfeed block is enabled on your site.
