IBM DataPower Gateway: Improper verification of cryptographic signature
Summary
IBM DataPower Gateway versions 10.5.0.0 to 10.5.0.22, 10.6.1 to 10.6.6, 10.6.0.0 to 10.6.0.10 and 11.0.0.0 to 11.0.0.2 do not properly verify cryptographic signatures. A remote attacker with valid low-privilege credentials can bypass security restrictions, with high impact on confidentiality and integrity. IBM rates the issue at CVSS 8.1.
Affected
- IBM DataPower Gateway 10.5.0.0 through 10.5.0.22
- IBM DataPower Gateway 10.6.1 through 10.6.6 (10.6CD)
- IBM DataPower Gateway 10.6.0.0 through 10.6.0.10
- IBM DataPower Gateway 11.0.0.0 through 11.0.0.2
Fixed in
- Upgrade to 11.0.0.3 for the 11.0.0 line and the 10.6CD line (10.6.1 to 10.6.6), according to the IBM bulletin mapping
- Upgrade to 10.6.0.11 for the 10.6.0 line
- Upgrade to 10.5.0.23 for the 10.5 line
- Confirm the exact mapping in the IBM bulletin before planning upgrades.
Workaround
Unknown.
Exploitation
- Not known to be exploited (CISA KEV: No).
- No public proof of concept found in the research; this does not rule one out.
- EPSS is low (about 0.56%).
Our recommendation
- Inventory all DataPower instances and their exact versions, and note which are reachable from the internet or partner networks.
- Upgrade to the fixed release specified in the IBM bulletin for each release line.
- Prioritise CVE-2026-14999 from the same IBM bulletin, which does not require authentication.
- Review and reduce accounts with access to DataPower, including admin and service accounts.
- Monitor for changes in KEV status and public proof-of-concept code.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
