Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Input validation error (CVE-ID: CVE-2022-29404)

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

The vulnerability exists due to insufficient validation of user-supplied input when processing HTTP requests to a lua script that calls r:parsebody(0). A remote attacker can send a very large HTTP request to the affected web server and perform a denial of service (DoS) attack.


2) Resource exhaustion (CVE-ID: CVE-2022-30522)

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

The vulnerability exists due to mod_sed does not properly control consumption of internal resources, if the web server is configured to do transformations with mod_sed in contexts where the input to mod_sed may be very large. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


3) Out-of-bounds read (CVE-ID: CVE-2022-30556)

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

The vulnerability exists due to a boundary condition when processing HTTP requests in mod_lua with websockets. A remote attacker can force the module to return lengths to applications calling r:wsread() that point past the end of the storage allocated for the buffer and gain access to sensitive information.


4) Improper Authentication (CVE-ID: CVE-2022-31813)

The vulnerability allows a remote attacker to bypass authentication process.

The vulnerability exists due to an error in mod_proxy implementation, where the web server may not send the X-Forwarded-* headers to the origin server based on client side Connection header hop-by-hop mechanism. A remote attacker can bypass IP based authentication on the origin server/application and gain access to otherwise restricted functionality.
