Detailsinfo

A vulnerability was found in IDEMIA SIGMA Lite & Lite +, SIGMA Wide, SIGMA Extreme, MorphoWave Compact, XP, VisionPass and MorphoWave SP. It has been classified as very critical. Affected is an unknown functionality of the component Retrofit Validation Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. CWE is classifying the issue as CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

During the retrofit validation process, the firmware doesn't properly check the boundaries while copying some attributes to check. This allows a stack-based buffer overflow that could lead to a potential Remote Code Execution on the targeted device

The weakness was disclosed 12/15/2023. The advisory is shared for download at idemia.com. This vulnerability is traded as CVE-2023-33220 since 05/18/2023.
