SB2024041653 - Multiple vulnerabilities in Oracle Communications Cloud Native Core Security Edge Protection Proxy

Description

This security bulletin contains information about 5 secuirty vulnerabilities.

1) Inefficient regular expression complexity (CVE-ID: CVE-2022-40896)

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

The vulnerability exists due to insufficient input validation when processing untrusted input with a regular expressions in pygments/lexers/smithy.py. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.

2) Input validation error (CVE-ID: CVE-2023-34055)

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 in Web Observations. A remote attacker can send specially crafted HTTP requests to the application and perform a denial of service (DoS) attack.

Successful exploitation of the vulnerability requires that application is using Spring MVC or Spring WebFlux and that org.springframework.boot:spring-boot-actuator is on the classpath.

3) Input validation error (CVE-ID: CVE-2024-22233)

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. A remote attacker can send specially crafted HTTP requests to the application and perform a denial of service (DoS) attack.

4) Resource exhaustion (CVE-ID: CVE-2023-44487)

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

The vulnerability exists due to improperly control of consumption for internal resources when handling HTTP/2 requests with compressed HEADERS frames. A remote attacker can send a sequence of compressed HEADERS frames followed by RST_STREAM frames and perform a denial of service (DoS) attack, a.k.a. "Rapid Reset".

Note, the vulnerability is being actively exploited in the wild.

5) NULL pointer dereference (CVE-ID: CVE-2023-49083)

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

The vulnerability exists due to a NULL pointer dereference error when calling the load_pem_pkcs7_certificates() or load_der_pkcs7_certificates() functions. A remote attacker can pass specially crafted PKCS7 blob/certificate certificate to the application and perform a denial of service (DoS) attack.
