Accessories and Display Manager: Improper Certificate Validation

CVE-2024-4762 is a high-severity improper certificate validation vulnerability in Accessories and Display Manager from Lenovo, with a CVSS 3.1 base score of 7.8 out of 10. It can be exploited with local access to the system by an attacker with a low-privileged account, without any action from a user. The record lists version 1.0.5.0.5 as the first without the flaw, so updating Accessories and Display Manager to that release or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.15% chance of exploitation within 30 days, which is low compared with other CVEs.

Official description

An improper validation vulnerability was reported in the firmware update mechanism of LADM and LDCC that could allow a local attacker to escalate privileges.

Source: the CVE record as published by its numbering authority, via NVD and CVE.org.

The underlying weakness: Improper Certificate Validation

The product does not validate, or incorrectly validates, a certificate.

How developers prevent this class of flaw

  • Certificates should be carefully managed and checked to assure that data are encrypted with the intended owner's public key.
  • If certificate pinning is being used, ensure that all relevant properties of the certificate are fully validated before the certificate is pinned, including the hostname.
