The flaw is a command injection vulnerability in the Spark UI of Apache Spark, reached through its access control checks when spark.acls.enable is set, where an impersonation path in HttpSecurityFilter lets user-supplied input flow into a Unix shell command. An attacker who can reach the Spark UI over the network and hold low-privileged credentials could exploit this without user interaction to run arbitrary shell commands as the user Spark runs as, provided ACLs are enabled and an authentication filter is in place.
** UNSUPPORTED WHEN ASSIGNED ** The Apache Spark UI offers the possibility to enable ACLs via the configuration option spark.acls.enable. With an authentication filter, this checks whether a user has access permissions to view or modify the application. If ACLs are enabled, a code path in HttpSecurityFilter can allow someone to perform impersonation by providing an arbitrary user name. A malicious user might then be able to reach a permission check function that will ultimately build a Unix shell command based on their input, and execute it. This will result in arbitrary shell command execution as the user Spark is currently running as. This issue was disclosed earlier as CVE-2022-33891, but incorrectly claimed version 3.1.3 (which has since gone EOL) would not be affected. NOTE: This vulnerability only affects products that are no longer supported by the maintainer. Users are recommended to upgrade to a supported version of Apache Spark, such as version 3.4.0.
Disclosed on 2 May 2023. No public exploit code or confirmed exploitation is recorded.
2 related vulnerabilities in the same code over 9 months.
Why these are linked: Link confidenceHow strong the evidence is that two CVEs are related. High: stated in the CVE text or linked in an advisory, or the same code was patched one release apart. Medium: the same code, or a version step plus a similar description. Low: similar description only.
No ATT&CK techniques are linked to this CVE yet. MITRE CTID has not mapped it, and no report passage in the corpus ties it to a technique.
