Security readout for executives and security teams
Plain-English summary
CVE-2020-10762 is a local information-disclosure issue in gluster-block. Older versions logged CLI operation output, including passwords, into a world-readable history log. A local user on the system could read that log and recover sensitive credentials.
Executive priority
Prioritize remediation where gluster-block runs on shared administrative hosts or where exposed credentials could unlock storage infrastructure. The issue is not documented as remotely exploitable, but credential leakage can create broader business risk.
Technical view
gluster-block before 0.5.1 wrote sensitive CLI output to cmd_history.log with overly permissive access. The weakness maps to CWE-732 and primarily affects confidentiality. The provided sources do not include CVSS scoring, remote exploitability, or confirmed exploitation.
Likely exposure
Exposure is likely limited to systems running gluster-block versions before 0.5.1 where untrusted or lower-privileged local users can read the cmd_history.log file.
Exploitation context
The source bundle supports local credential disclosure only. CISA KEV is false, and no cited source confirms active exploitation or public exploit use.
Researcher notes
The core evidence is clear on local password disclosure via world-readable logging. Severity metadata is incomplete, and the source bundle has limited affected-version detail beyond “before 0.5.1,” so verify vendor release notes before final scoping.
Mitigation direction
- Inventory systems running gluster-block and confirm whether versions are before 0.5.1.
- Review vendor guidance and move affected deployments to a fixed supported release.
- Restrict local user access to systems hosting gluster-block management tooling.
- Treat any exposed logged passwords as compromised and rotate them.
- Review log retention and permissions for cmd_history.log and related operational logs.
Validation and detection
- Confirm installed gluster-block versions across affected hosts.
- Check whether cmd_history.log exists and is world-readable.
- Determine whether cmd_history.log contains passwords or other secrets.
- After remediation, verify CLI operations no longer expose passwords in readable logs.
- Review local accounts that could have accessed the log.

Incorrect Permission Assignment for Critical Resource
Incorrect Permission Assignment for Critical Resource represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
