FreeBSD : Apache Tomcat -- RCE due to TOCTOU issue in JSP compilation (ed0a052a-c5e6-11ef-a457-b42e991fc52e)

critical Nessus Plugin ID 213442

Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The version of FreeBSD installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the ed0a052a-c5e6-11ef-a457-b42e991fc52e advisory.

 [email protected] reports:
 Time-of-check Time-of-use (TOCTOU) Race Condition The mitigation for CVE-2024-50379 was incomplete.
 Users running Tomcat on a case insensitive file system with the default servlet write enabled (readonly initialisation parameter set to the non-default value of false) may need additional configuration to fully mitigate CVE-2024-50379 depending on which version of Java they are using with Tomcat: - running on Java 8 or Java 11: the system propertysun.io.useCanonCaches must be explicitly set to false (it defaults to true) - running on Java 17: thesystem property sun.io.useCanonCaches, if set, must be set to false(it defaults to false) - running on Java 21 onwards: no further configuration is required(the system property and the problematic cache have been removed) Tomcat 11.0.3, 10.1.35 and 9.0.99 onwards will include checks thatsun.io.useCanonCaches is set appropriately before allowing the default servlet to be write enabled on a case insensitive file system. Tomcat will also setsun.io.useCanonCaches to false by default where it can.

Tenable has extracted the preceding description block directly from the FreeBSD security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the affected packages.
