## Technical details

An SQL injection vulnerability exists in the J-ClassifiedsManager component (version 3.0.5 and below) for Joomla. The flaw is located within the 'displayads' component, specifically failing to properly sanitize the 'categorySearch', 'adType', and 'citySearch' POST parameters. An unauthenticated remote attacker can send crafted SQL payloads to these parameters to perform out-of-band or error-based data extraction. This allows for the retrieval of sensitive information from the underlying database, such as database names, version information, and user tables. While the vulnerability was publicly disclosed with a proof-of-concept in 2019, it was formally assigned a CVE in 2026.
