CVE-2023-22946
Safety vulnerability ID: SFTY-20230417-69236
Safety legacy ID: pyup.io-62892
Affected versions of the Apache Spark package are vulnerable to Improper Input Validation due to insufficient restrictions on classpath configurations. The vulnerability exists because applications can specify arbitrary configuration-related classes on the classpath, circumventing the intended privilege limitations imposed by the 'proxy-user' setting. An attacker can exploit this by submitting a malicious application that includes custom classpath entries, allowing execution of code with the privileges of the submitting user rather than the restricted proxy-user, potentially compromising system security.
