Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Authentication to the admin panel is required - the CVSS PR:L (Low Privileges) vector confirms that a valid account with access to the /admin/ section must be obtained before exploitation is possible; unauthenticated remote exploitation is not supported by the available data. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 2.1 (Low) with vector AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L reflects network-reachable exploitation requiring low privilege and no user interaction, but with only partial confidentiality, integrity, and availability impact and no scope change to secondary systems. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who has obtained valid low-privileged admin credentials - through phishing, credential stuffing, or brute force against the admin panel - navigates to /admin/addproduct.php and submits a product creation request with a PHP web shell renamed to bypass any client-side extension checks, uploading it via the image parameter. A public proof-of-concept demonstrating this exact technique is available at the GitHub gist referenced in the CVE. … |
| Remediation | No vendor-released patch has been identified at time of analysis - no fix version appears in any referenced source including VulDB, NVD, or the SourceCodester vendor site. … Detailed patch versions, workarounds, and compensating controls in full report. |
