Vulnerability AssessmentAI

Risk Assessment The CVSS 4.0 vector confirms this is a network-exploitable vulnerability requiring no authentication (PR:N), no special user interaction (UI:N), and minimal attack complexity (AC:L), yielding a base score of 6.9 with low confidentiality, integrity, and availability impact (VC:L/VI:L/VA:L). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker crafts a malicious HTTP POST or GET request to the /addcat.php endpoint with a specially formed cata parameter containing SQL metacharacters and a UNION-based injection payload (e.g., cata=test' UNION SELECT user(),version()--). The unfiltered input reaches the database query, allowing the attacker to extract usernames, password hashes, or other sensitive data from the database, or potentially escalate to arbitrary file read/write if database functions permit. …
Remediation Upgrade Lost and Found Thing Management to a patched version if released by code-projects; check https://code-projects.org/ for updates. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
