Security Bulletin

1) Permissions, Privileges, and Access Controls

EUVDB-ID: #VU101814

Risk: Medium

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2024-50379

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: Yes

Description

The vulnerability allows a remote attacker to compromise the affected system.

The vulnerability exists due to missing access restrictions to the default servlet. If the default servlet is write enabled (readonly initialisation parameter set to the non-default value of false) for a case insensitive file system, concurrent read and upload under load of the same file can bypass Tomcat's case sensitivity checks and cause an uploaded file to be treated as a JSP leading to remote code execution.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Confluence Data Center: 6.10.0 - 9.2.0

Atlassian Confluence Server: 6.10.0 - 9.2.0
