AI Analysis

Impact

The vulnerability allows a local attacker with access to a vulnerable IBM Db2 installation to use the db2pd utility to gain higher privileges, potentially enabling full system control. The flaw is a classic privilege escalation weakness, classified as CWE-269, and could enable modification of system settings or data. The CVSS score of 6.5 indicates a moderate severity impact but the ability to elevate privileges remains a serious threat, especially in environments where administrators rely on strong segregation of roles.

Affected Systems

IBM Db2 releases 11.5.0 through 11.5.9 and 12.1.0 through 12.1.5 are affected on both AIX and Linux platforms. The specific releases that have patch availability include version 11.5.9 for the 11.5 line and 12.1.4/12.1.5 for the 12.1 line. Administrators can apply the security updates listed in Fix Central for the corresponding release levels to remediate the issue.

Risk and Exploitability

The CVSS score of 6.5 reflects a moderate risk, and there is no EPSS score information available to indicate current exploitation probability. The vulnerability is not listed in CISA KEV, suggesting it has not yet been widely exploited in known campaigns. Because the attack requires local access and manipulation of the db2pd utility, an attacker must already have a foothold on the machine, such as a user account with limited privileges, to exploit the flaw. Once accessed, an attacker could elevate privileges and bypass security controls on the affected Db2 system.

These security updates are available based on the most recent level for each impacted release: V11.5.9, V12.1.4, and V12.1.5. They can be applied to any affected level of the appropriate release to remediate this vulnerability. ReleaseFixed in mod packAPARDownload URLV11.5TBD https://www.ibm.com/support/pages/node/7087189 V12.1TBD https://www.ibm.com/support/pages/node/7267513 Security Update #94858 or later for V12.1.5 available at this link: https://www.ibm.com/support/pages/node/7282633 IBM does not disclose key Db2 functionality nor replication steps for a vulnerability to avoid providing too much information to any potential malicious attacker. IBM does not want to enable a malicious attacker with sufficient knowledge to craft an exploit of the vulnerability.


OpenCVE Recommended Actions

  • Install the IBM Db2 security update for the affected release level (e.g., V11.5.9 for 11.5, V12.1.4 or V12.1.5 for 12.1) as provided on Fix Central.
  • Restrict execution of the db2pd utility so that only privileged administrative accounts can run it, removing default execution permissions for non‑privileged users.
  • Monitor system logs for unusual db2pd activity, especially attempts by low‑privilege accounts to invoke the utility.
