DescriptionNVD

Dell Display and Peripheral Manager (DDPM Mac), versions prior to 2.3, contain an Improper Certificate Validation vulnerability. A low privileged attacker with local access could potentially exploit this vulnerability, leading to Protection mechanism bypass.

AnalysisAI

Protection mechanism bypass in Dell Display and Peripheral Manager for Mac (versions prior to 2.3) stems from improper certificate validation, allowing a low-privileged local user to defeat a security control the application relies on. Dell self-reported the issue and there is no public exploit identified at time of analysis; EPSS is very low (0.07%) and CISA SSVC marks exploitation status as 'none', though technical impact is rated 'total'. The flaw affects the macOS build of DDPM, a companion utility for Dell monitors and peripherals.
