IBM DataStage on Cloud Pak for Data: Path traversal allows denial of service
Summary
IBM DataStage on Cloud Pak for Data 5.4.0.0 contains a path traversal vulnerability (CWE-22). A remote attacker with a valid low-privilege account can cause a denial of service. IBM's bulletin also describes a CVSS vector with high integrity impact, which does not match the description, so the vector should be verified. No public exploit code or KEV listing was found at the time of research.
Affected
- IBM DataStage on Cloud Pak for Data 5.4.0.0
Fixed in
- Upgrade to 5.4 patch 7 or later, per IBM's instructions (https://www.ibm.com/docs/en/software-hub/5.4.x)
Workaround
Unknown.
Exploitation
- No public proof of concept confirmed at the time of research.
- Not listed in CISA KEV at the time of research.
- CISA SSVC: exploitation none, not automatable, partial technical impact.
Our recommendation
- Check whether DataStage on Cloud Pak for Data 5.4.0.0 is deployed.
- Apply the IBM fix (5.4 patch 7 or later) as part of the whole IBM bulletin for this product, not only this CVE.
- Restrict access to the platform to trusted users and networks, and review user accounts with access.
- Do not expose the Cloud Pak for Data interface directly to the internet.
- Monitor for exploitation and recheck CISA KEV and exploit status regularly.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.
