Technical impact
The vulnerability manifests as an improper certificate validation in Dell Display and Peripheral Manager (DDPM) for macOS, before version 2.3. By forging a trusted certificate, a local attacker can trick DDPM into accepting the certificate, effectively bypassing the driver’s protection mechanisms. This flaw, classified as CWE‑295, permits the attacker to elevate privileges within the protected environment and potentially install malicious software or access restricted resources.
Affected Systems
Dell Display and Peripheral Manager (DDPM) for macOS, all releases earlier than 2.3. The flaw applies to any Dell system that ships with this older DDPM version and grants local access.
Risk and Exploitability
The CVSS score of 7.3 indicates a high severity risk. Exploitation requires a low‑privileged attacker to gain local access to the target machine. No EPSS data is available and the vulnerability is not listed in the CISA KEV catalog, so no widespread exploitation is reported. Nonetheless, once an attacker achieves local access, the improper certificate validation allows a breach of the protection mechanisms designed to guard against tampering and secure communications. Attackers would insert a counterfeit CA certificate or use a crafted DDPM package to cause DDPM to accept untrusted certificates, thereby gaining an advantage in the system.
