DescriptionCVE.org

A weakness has been identified in code-projects Online Job Portal 1.0. This affects an unknown function of the file /JobSeekerInsert.php. Executing a manipulation of the argument txtFile can lead to unrestricted upload. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks.

AnalysisAI

Unrestricted file upload in code-projects Online Job Portal 1.0 exposes unauthenticated remote attackers to arbitrary file upload via the txtFile parameter in /JobSeekerInsert.php, enabling likely webshell deployment and subsequent server-side code execution. A public proof-of-concept exploit exists (no KEV listing), substantially lowering the exploitation barrier for any internet-exposed instance. …

Vulnerability AssessmentAI

Exploitation The /JobSeekerInsert.php endpoint must be publicly reachable over the network. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 base vector (AV:N/AC:L/AT:N/PR:N/UI:N) confirms network-accessible, zero-complexity, unauthenticated exploitation with no user interaction required - maximum accessibility for a remote flaw. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An unauthenticated attacker sends a crafted HTTP POST request to /JobSeekerInsert.php with a PHP webshell (e.g., <?php system($_GET['cmd']); ?>) supplied as the txtFile parameter value. The server stores the file without validating its type, and the attacker then issues a GET request to the uploaded file's web-accessible path with an OS command in the query string, achieving arbitrary command execution as the web server user. …
Remediation No vendor-released patch has been identified at time of analysis; fix version is unknown and unconfirmed. … Detailed patch versions, workarounds, and compensating controls in full report.
