CVE-2024-2243
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedA vulnerability was found in csmock where a regular user of the OSH service (anyone with a valid Kerberos ticket) can use the vulnerability to disclose the confidential Snyk authentication token and to run arbitrary commands on OSH workers.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceIn csmock, a regular user with a valid Kerberos ticket can exploit an authorization flaw to disclose the confidential Snyk authentication token and execute arbitrary commands on OSH worker systems. This indicates a privilege escalation or improper access control vulnerability where authenticated users can bypass intended restrictions on sensitive credential access and command execution.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify installed csmock versionRun 'rpm -qa | grep csutils' or 'pip list | grep csutils' to find the csutils package version that includes csmockAffected if The installed version is lower than 3.5.3
-
Check if Kerberos authentication is configured for OSH servicesReview /etc/csmock or /etc/osh related configuration files for Kerberos (krb5) settings, and check if the OSH service accepts Kerberos-authenticated connectionsAffected if Kerberos authentication is enabled and the OSH service is configured to accept Kerberos tickets from regular users
-
Verify presence of Snyk token configurationSearch for Snyk API token in environment variables (env | grep -i snyk), configuration files (/etc/csmock/*.conf, ~/.csmockrc), or in OSH worker configurationsAffected if A Snyk authentication token is configured in the environment or in csmock configuration files accessible to authenticated users
-
Check OSH worker service accessibilityDetermine if the OSH service (osh-worker) is running and reachable by authenticated users; inspect whether unauthenticated or low-privilege Kerberos users can submit requests to the OSH serviceAffected if OSH worker systems are accessible to authenticated Kerberos users without proper authorization controls
A user is affected if they have csmock version below 3.5.3 with Kerberos authentication enabled and a Snyk token configured in an accessible location, allowing other Kerberos-authenticated users to potentially retrieve the token or execute commands via the OSH service.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped3.5.3
Immediately rotate the exposed Snyk authentication token and apply any available patches or updates to csmock to fix the improper authorization logic. Review and restrict what authenticated Kerberos users can access within the OSH service.
csmock 3.5.3
- Upgrade csmock to version 3.5.3 or later to resolve the OS command injection vulnerability
- Verify the upgrade was successful by checking the installed csmock version using 'csmock --version' or equivalent
