CVE-2024-31870

Local user enumeration via missing object authorization

Published Jun 15, 2024 · Updated Aug 22, 2024

Information disclosure in IBM Db2 7.2 through 7.5 allows local users to enumerate user-profile names through a supplied table function. The function returns profile names without enforcing the caller's authority to the related *USRPRF objects; IBM has not publicly named the function. Access requires a locally authenticated low-privileged account, and the disclosed names support later targeting without exposing profile contents or granting added authority.
