IBM Maximo AI Service: Code injection enables remote code execution
Summary
IBM Maximo AI Service versions 9.1.0 and 9.2.0 contain a code injection flaw (CWE-94) that allows a remote attacker to execute arbitrary code. Per the CVSS vector, no privileges or user interaction are required over the network, and the impact on confidentiality, integrity and availability is rated high. The vendor's information does not describe a prerequisite beyond network reachability of the affected service.
Affected
- IBM Maximo AI Service 9.1.0
- IBM Maximo AI Service 9.2.0
Fixed in
- Maximo AI Service 9.1.19 or the latest release (available from the Catalog under Update Available)
- Maximo AI Service 9.2.3 or the latest release (available from the Catalog under Update Available)
Workaround
Unknown. No workaround is documented in the sources reviewed; upgrading is the only fix named.
Exploitation
- No evidence of in-the-wild exploitation found; not listed in CISA KEV according to Strix.
- CISA SSVC: Exploitation none, Automatable yes, Technical Impact total.
- No public proof-of-concept confirmed.
- EPSS 0.00544 (low predicted exploitation probability).
Our recommendation
- Check whether IBM Maximo AI Service is installed and whether its endpoints are reachable from the internet.
- Restrict network access to Maximo AI Service endpoints until the upgrade is done.
- Upgrade to 9.1.19 or 9.2.3 (or later) as listed in the IBM advisory.
- Monitor logs for unexpected code execution or suspicious requests to the service.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
