A weakness has been identified in SourceCodester Simple Online Food Ordering System 1.0. This vulnerability affects unknown code of the file /fos/admin/ajax.php?action=save_user. This manipulation of the argument Username causes sql injection. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks.
AnalysisAI
SQL injection in SourceCodester Simple Online Food Ordering System 1.0 exposes the admin AJAX endpoint /fos/admin/ajax.php?action=save_user to remote database manipulation via an unsanitized Username parameter. The CVSS 4.0 vector (AV:N/AC:L/PR:N/UI:N) confirms unauthenticated network exploitation with no user interaction required, meaning any internet-facing instance is trivially reachable. …

Vulnerability AssessmentAI
| Exploitation | The CVSS 4.0 base vector (AV:N/AC:L/AT:N/PR:N/UI:N) indicates no special conditions are required on the attacker's side - exploitation requires only that the /fos/admin/ajax.php endpoint be reachable over the network, which is the default posture for web-facing deployments of this application. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 score of 5.5 (Medium) reflects constrained impact: all three vulnerable-system metrics (VC:L/VI:L/VA:L) are Low, and there is no scope change to subsequent systems (SC:N/SI:N/SA:N). … 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 /fos/admin/ajax.php?action=save_user on an internet-exposed instance, embedding SQL injection payloads (e.g., UNION SELECT or stacked queries) in the Username parameter. Because public exploit code is referenced in the GitHub issue at https://github.com/wsx138/cve/issues/3, this requires minimal attacker skill and can be adapted from standard SQLi tooling such as sqlmap. … |
| Remediation | No vendor-released patch has been identified at time of analysis - the fix status is unconfirmed per available references. … Detailed patch versions, workarounds, and compensating controls in full report. |
