Vulnerability AssessmentAI
| Exploitation | The only prerequisite is that ajax.php is reachable over the network, which is the default deployment posture for a web-based payroll application. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 6.9 encodes network accessibility (AV:N), low complexity (AC:L), no privileges required (PR:N), and no user interaction (UI:N), with partial impact across confidentiality, integrity, and availability (VC:L/VI:L/VA:L). … 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 the publicly accessible ajax.php endpoint with a manipulated 'action' parameter value targeting a CRUD operation - for example, listing all employee salary records or modifying a specific record. With the proof-of-concept code available at https://github.com/microwaveabi/vul/issues/7, exploitation requires only knowledge of the target URL and the parameter structure, with no credentials or prior access. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the disclosure was made through VulDB (https://vuldb.com/vuln/395909) with no corresponding patch release from itsourcecode.com confirmed. … Detailed patch versions, workarounds, and compensating controls in full report. |
