Description

This security bulletin contains information about 3 secuirty vulnerabilities.


1) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2021-21295)

The vulnerability allows a remote attacker to preform HTTP request smuggling attacks.

The vulnerability exists due to improper validation of HTTP requests in io.netty:netty-codec-http2 when converting HTTP/2 to HTTP/1 streams. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.

Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.


2) Code Injection (CVE-ID: CVE-2024-12798)

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

The vulnerability exists due to improper input validation in JaninoEventEvaluator extension when handling environment variables. A local user can inject specially crafted data into environment variables and execute arbitrary code with elevated privileges.


3) XML External Entity injection (CVE-ID: CVE-2024-12801)

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

The vulnerability exists due to insufficient validation of user-supplied XML input in SaxEventRecorder. A remote attacker can pass a specially crafted configuration XML file to the affected application and view contents of arbitrary files on the system or initiate requests to external systems.

Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
