CVE-2011-3629: 
Joomla vulnerability analysis and mitigation

Joomla! core version 1.7.1 was found to contain an information disclosure vulnerability due to weak encryption implementation. The vulnerability was assigned CVE-2011-3629 and was initially reported on September 21, 2011 (CVE MITRE).

The vulnerability stems from weak encryption mechanisms implemented in Joomla! core 1.7.1 that could potentially lead to information disclosure. This security issue was later clarified to be distinct from other similar vulnerabilities reported around the same time, specifically focusing on the weak encryption implementation rather than other information disclosure vectors (OSS Security).

The vulnerability could result in unauthorized information disclosure due to the weak encryption implementation in the affected Joomla! version (Joomla Security).

There was some initial confusion in the security community regarding the proper CVE assignment, as multiple information disclosure vulnerabilities were discovered in Joomla! around the same time. This led to discussions between security researchers and Red Hat's Security Response Team to properly categorize and assign distinct CVE identifiers to each unique vulnerability (OSS Security Discussion).
