TencentOS Server 4: tomcat (TSSA-2024:1139)

high Nessus Plugin ID 239620

Synopsis

The remote TencentOS Server 4 host is missing one or more security updates.

Description

The version of Tencent Linux installed on the remote TencentOS Server 4 host is prior to tested version. It is, therefore, affected by multiple vulnerabilities as referenced in the TSSA-2024:1139 advisory.

Package updates are available for TencentOS Server 4 that fix the following vulnerabilities:

CVE-2024-56337:
Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability in Apache Tomcat.

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.0.97.

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.

CVE-2024-54677:
Uncontrolled Resource Consumption vulnerability in the examples web application provided with Apache Tomcat leads to denial of service.

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.9.97.

Users are recommended to upgrade to version 11.0.2, 10.1.34 or 9.0.98, which fixes the issue.

CVE-2024-50379:
Time-of-check Time-of-use (TOCTOU) Race Condition vulnerability during JSP compilation in Apache Tomcat permits an RCE on case insensitive file systems when the default servlet is enabled for write (non-default configuration).

This issue affects Apache Tomcat: from 11.0.0-M1 through 11.0.1, from 10.1.0-M1 through 10.1.33, from 9.0.0.M1 through 9.0.97.

Users are recommended to upgrade to version 11.0.2, 10.1.34 or 9.0.08, which fixes the issue.

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

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

Solution
