Vulnerability AssessmentAI
| Exploitation | No authentication is required - the vulnerable parameter (Username) is exposed on the pre-authentication login form, accessible to any network-reachable client. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.5 (Medium) with AV:N/AC:L/AT:N/PR:N/UI:N presents an attacker-favorable exploitation profile - unauthenticated, low complexity, fully remote, no user interaction required. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated remote attacker submits a crafted HTTP POST request to the Payroll System login page, injecting a SQL payload such as `' OR '1'='1' --` into the Username field. The admin_class.php Login function passes this unsanitized input directly into a SQL query, causing the database to evaluate the injected condition and either bypass authentication entirely or return database rows. … |
| Remediation | No vendor-released patch has been identified at time of analysis. … Detailed patch versions, workarounds, and compensating controls in full report. |
