When serving resources from a network location using the NTFS file system, Apache Tomcat versions 10.0.0-M1 to 10.0.0-M9, 9.0.0.M1 to 9.0.39, 8.5.0 to 8.5.59 and 7.0.0 to 7.0.106 were susceptible to JSP source code disclosure in some configurations. The root cause was the unexpected behaviour of the JRE API File.getCanonicalPath() which in turn was caused by the inconsistent behaviour of the Windows API (FindFirstFileW) in some circumstances.

The version of tomcat installed on the remote host is prior to 8.5.60-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2TOMCAT8.5-2023-010 advisory.

    While investigating bug 64830 it was discovered that Apache Tomcat 10.0.0-M1 to 10.0.0-M9, 9.0.0-M1 to     9.0.39 and 8.5.0 to 8.5.59 could re-use an HTTP request header value from the previous stream received on     an HTTP/2 connection for the request associated with the subsequent stream. While this would most likely     lead to an error and the closure of the HTTP/2 connection, it is possible that information could leak     between requests. (CVE-2020-17527)

According to the versions of the tomcat packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - When serving resources from a network location using     the NTFS file system, Apache Tomcat versions 10.0.0-M1     to 10.0.0-M9, 9.0.0.M1 to 9.0.39, 8.5.0 to 8.5.59 and     7.0.0 to 7.0.106 were susceptible to JSP source code     disclosure in some configurations.

  - The fix for CVE-2020-9484 was incomplete. When using     Apache Tomcat 10.0.0-M1 to 10.0.0, 9.0.0.M1 to 9.0.41,     8.5.0 to 8.5.61 or 7.0.0. to 7.0.107 with a     configuration edge case that was highly unlikely to be     used, the Tomcat instance was still vulnerable to     CVE-2020-9494. Note that both the previously published     prerequisites for CVE-2020-9484 and the previously     published mitigations for CVE-2020-9484 also apply to     this issue.(CVE-2021-25329)

This     JSP could then be requested and any code it contained would be executed by the server. (CVE-2017-12617)
