Description

This security bulletin contains information about 6 vulnerabilities.


1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2024-50379)

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

CVSSv4: 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


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.


2) Permissions, privileges, and access controls (CVE-ID: CVE-2024-56337)

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

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber


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

The vulnerability exists due to incomplete mitigation for #VU101814(CVE-2024-50379) on a case insensitive file system with the default servlet write enabled (readonly initialisation parameter set to the non-default value of false). A remote attacker can upload malicious files to the server and execute them compromising the system.

The mitigation bypass depends on the version of Java used on the system.


3) Resource exhaustion (CVE-ID: CVE-2024-54677)

CWE-ID: CWE-400 - Resource exhaustion

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green


The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to the examples web application does not properly control consumption of internal resources. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


4) Resource management error (CVE-ID: CVE-2024-52317)

CWE-ID: CWE-399 - Resource Management Errors

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Green


The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to improper management of internal resources when handling HTTP/2 responses, which causes request and/or response mix-up between users. A remote non-authenticated attacker can send a series of HTTP/2 requests and gain access to sensitive information.


5) Improper Certificate Validation (CVE-ID: CVE-2026-6900)

CWE-ID: CWE-295 - Improper Certificate Validation

CVSSv4: 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:U/U:Amber


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

The vulnerability exists due to improper certificate validation in the LDAP Server Connector. A remote attacker can perform adversary-in-the-middle attack and gain access to sensitive information on the system.


6) Untrusted search path (CVE-ID: CVE-2026-6901)

CWE-ID: CWE-426 - Untrusted Search Path

CVSSv4: CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to usage of an untrusted search path in the webserver. A local user can gain elevated privileges on the target system.
