1DescriptionCVE.org
Vulnerability involving incorrect access control in the Tools::getRemoteAddr() function in PrestaShop, which allows the client’s IP address to be spoofed via the X-Forwarded-For header when the application is running behind a reverse proxy, load balancer or CDN. The application incorrectly processes the IP address string and uses the address controlled by the visitor rather than the one provided by the trusted infrastructure, allowing an unauthenticated remote attacker to cause the application to interpret their connection as originating from an arbitrary IP address. This condition allows IP-based controls, such as the maintenance mode allowlist, to be bypassed, as well as enabling the forgery of security and audit logs and the evasion of third-party mechanisms that rely on the IP address, such as geolocation checks, fraud detection or request throttling.
AnalysisAI
IP address spoofing via X-Forwarded-For header manipulation in PrestaShop's Tools::getRemoteAddr() function allows unauthenticated remote attackers to impersonate arbitrary IP addresses when the application runs behind a reverse proxy, load balancer, or CDN. Affected versions include PrestaShop branches prior to 9.1.5 and prior to 8.2.8. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the PrestaShop instance is deployed behind a reverse proxy, load balancer, or CDN that passes client IP via the X-Forwarded-For header - the standard and near-universal production configuration. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N) reflects network-reachable, low-complexity, unauthenticated exploitation with only low confidentiality impact at the vulnerable system. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade PrestaShop to version 9.1.5 or later on the 9.x branch, or to version 8.2.8 or later on the 8.x branch, per the vendor patch confirmed in the INCIBE advisory (https://www.incibe.es/en/incibe-cert/notices/aviso/incorrect-access-control-prestashop). … Detailed patch versions, workarounds, and compensating controls in full report. |
