Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to hold an authenticated session with low-privilege access to the application's admin panel (/admin/ path), as confirmed by the CVSS 4.0 PR:L metric. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base score of 2.1 is notably low for a SQL injection vulnerability, primarily driven by the PR:L (low privilege) requirement and the low-impact ratings across VC:L/VI:L/VA:L with no scope change to subsequent systems. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker who has obtained or guessed low-privilege admin credentials for the Leave Management System navigates to /SimpleOnlineLeave/admin/deletemp.php and submits a crafted HTTP request with a SQL injection payload in the 'ID' parameter (e.g., ID=1 OR 1=1--). Because the parameter is concatenated unsanitized into a backend SQL query, the attacker can enumerate table contents, extract employee records, or modify leave data. …
Remediation No vendor-released patch has been identified at time of analysis for CodeAstro Simple Online Leave Management System 1.0; the disclosure appears to have been made via VulDB (https://vuldb.com/vuln/377907) and a GitHub proof-of-concept (https://github.com/sl1der-fr0g/Findings/issues/2) without an accompanying vendor fix announcement. … Detailed patch versions, workarounds, and compensating controls in full report.
