CVE-2023-43139Network attack vector

Unauthenticated code execution via payment validation command injection

Published Oct 31, 2023 · Updated Sep 17, 2024

OS command injection in the Franfinance module before 2.0.27 allows remote attackers to execute arbitrary code during payment validation. The payment-validation handlers send Atos SIPS v1 response data to a decryption binary through PHP exec(), allowing an injected executable script to enter that sequence. Versions before 1.9.0 on PrestaShop 1.6 are reachable even when disabled; versions before 2.0.27 on PrestaShop 1.7 require the module to be enabled.
