IBM Planning Analytics: Stack-based buffer overflow allows code execution
Summary
IBM Planning Analytics versions 2.0 and 2.1 contain a stack-based buffer overflow (CWE-121). A remote attacker with valid low-privileged credentials can exploit it to execute arbitrary code on the server. The CVSS 3.1 vector (AV:N/AC:L/PR:L) indicates a network attack that requires authentication but no user interaction, with high confidentiality and integrity impact.
Affected
- IBM Planning Analytics 2.0
- IBM Planning Analytics 2.1
- IBM Planning Analytics Local (Planning Analytics Workspace component)
Fixed in
Unknown. The fixed build for this CVE is not confirmed in the sources reviewed. IBM Planning Analytics Local 2.1.24 is referenced in the IBM bulletin; verify it covers this CVE.
Workaround
- No vendor workaround identified. Confirm in the IBM bulletin.
Exploitation
- No public proof-of-concept known.
- No evidence of exploitation in the wild; not listed in CISA KEV at the time of research.
- EPSS 0.0036.
Our recommendation
- Confirm the fixed build for 2.0 and 2.1 in IBM bulletin 7291604 or Fix Central and patch as soon as possible.
- Restrict network access to Planning Analytics servers to internal networks or VPN users.
- Review and reduce accounts that can authenticate; enforce strong, unique passwords.
- Monitor servers for unusual crashes or process behaviour.
- Priority: high if reachable beyond the internal LAN, medium if internal-only with restricted accounts.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
