CVE-2021-47966: PHP Timeclock 1.04 SQL Injection via login.php
PHP Timeclock 1.04 contains time-based and boolean-based blind SQL injection vulnerabilities in the login_userid parameter of login.php that allows unauthenticated attackers to extract database contents. Attackers can submit crafted POST requests with SQL payloads using SLEEP functions or RLIKE conditional statements to dump sensitive database information including employee names and credentials.
Security readout for executives and security teams
PHP Timeclock 1.04 has an unauthenticated SQL injection in its login page. A remote attacker could use the vulnerable login_userid field to extract database contents, including employee names and credentials. The bundle does not identify a vendor patch or confirm active exploitation. Exposure is most likely where PHP Timeclock 1.04 is deployed and reachable by untrusted users, especially internet-facing login pages. Organizations using this legacy SourceForge-hosted application should assume sensitive personnel and credential data may be at risk until version and exposure are verified. Treat this as a high-priority exposure review if PHP Timeclock is still in use. The business risk is credential and employee data compromise from an unauthenticated web attack. Prioritize internet-facing systems first, then internal deployments reachable by broad user populations. Mitigation focus: Inventory PHP Timeclock deployments and identify any version 1.04 instances.; Restrict network access to login.php until vendor guidance is confirmed.; Check the vendor and project pages for patch, upgrade, or retirement guidance..

CWE-89: Database access and collection lookup
Injection into data stores can inform collection, data access, and exfiltration detection reviews. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
The CVE wording references database injection or access, so collection and exfiltration review may help. This is a Glexia inferred lookup path, not an official MITRE, ATT&CK, or CVE Program mapping.
These fields come from the CVE record and ADP containers, not from Glexia's Take. They preserve time-varying source decisions such as CISA SSVC, KEV status, CVSS metrics, and provider references.
We collect every scored CVSS vector available in the official CNA and ADP containers. When more than one version is present, the table keeps the source vectors side by side instead of collapsing them into the highest score.

Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')
Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
