DescriptionCVE.org

A weakness has been identified in code-projects Employee Management System 1.0. Affected by this vulnerability is an unknown functionality of the file /process/applyleaveprocess.php. This manipulation of the argument ID causes sql injection. The attack can be initiated remotely. The exploit has been made available to the public and could be used for attacks.

AnalysisAI

SQL injection in code-projects Employee Management System 1.0 allows remote low-privileged attackers to manipulate the ID parameter in /process/applyleaveprocess.php, enabling unauthorized database read and write operations with partial impact across confidentiality, integrity, and availability. A publicly available proof-of-concept exploit exists on GitHub, though no confirmed active exploitation (CISA KEV) has been recorded. …

Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold a valid low-privilege account on the target Employee Management System 1.0 instance, as confirmed by PR:L in the CVSS 4.0 vector - unauthenticated exploitation is not supported by the available data. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 2.1 (Low) reflects the PR:L requirement and partial-only impact across VC:L/VI:L/VA:L with no scope change to secondary systems (SC:N/SI:N/SA:N). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An authenticated low-privilege employee submits a crafted HTTP request to `/process/applyleaveprocess.php` with an `ID` parameter containing injected SQL syntax such as `1 UNION SELECT username,password,null FROM users--`. The backend SQL query is rewritten by the injected payload, returning rows from unintended tables and exposing credential hashes or sensitive HR records. …
Remediation No vendor-released patch has been identified at time of analysis; monitor https://code-projects.org/ and VulDB entry https://vuldb.com/vuln/365432 for updates. … Detailed patch versions, workarounds, and compensating controls in full report.
