Deeper analysis
CVE-2020-37151 is a SQL injection vulnerability affecting phpMyChat Plus version 1.98, specifically in the deluser.php page through the pmc_username parameter. This flaw allows attackers to manipulate database queries by injecting malicious payloads into the username field, enabling boolean-based, error-based, and time-based blind SQL injection techniques to extract sensitive database information.
The vulnerability has a CVSS v3.1 base score of 8.2 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N), indicating it is exploitable over the network with low complexity, no privileges or user interaction required. Remote unauthenticated attackers can craft payloads to read confidential data from the database, with high impact on confidentiality and low impact on integrity, but no denial-of-service potential.
Advisories and related resources, including an exploit on Exploit-DB (https://www.exploit-db.com/exploits/48066), a Vulncheck advisory (https://www.vulncheck.com/advisories/phpmychat-plus-deluserphp-sql-injection), and the phpMyChat Plus site (http://ciprianmp.com/latest/), document the issue and provide proof-of-concept details, emphasizing the need for input validation or upgrading to a patched version where available.
