SB20221018105 - Multiple vulnerabilities in Oracle Communications Cloud Native Core Security Edge Protection Proxy

Description

This security bulletin contains information about 6 secuirty vulnerabilities.

1) Resource exhaustion (CVE-ID: CVE-2022-32206)

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

The vulnerability exists due to insecure processing of compressed HTTP responses. A malicious server can send a specially crafted HTTP response to curl and perform a denial of service attack by forcing curl to spend enormous amounts of allocated heap memory, or trying to and returning out of memory errors.

2) Buffer overflow (CVE-ID: CVE-2018-25032)

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 compressing data. A remote attacker can pass specially crafted input to the application, trigger memory corruption and perform a denial of service (DoS) attack.

3) Resource exhaustion (CVE-ID: CVE-2022-25857)

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

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

4) Out-of-bounds read (CVE-ID: CVE-2022-1586)

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

The vulnerability exists due to a boundary condition in the PCRE2 library in the compile_xclass_matchingpath() function of the pcre2_jit_compile.c file. A remote attacker can pass specially crafted data to the application, trigger out-of-bounds read error, gain access to sensitive information or perform a denial of service attack.

5) OS Command Injection (CVE-ID: CVE-2022-1292)

The vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.

The vulnerability exists due to improper input validation in the c_rehash script distributed by some operating systems. A remote attacker with ability to pass data to c_rehash script can and execute arbitrary OS commands with the privileges of the script.

6) Improper Authorization (CVE-ID: CVE-2022-22978)

The vulnerability allows a remote attacker to bypass authorization process.

The vulnerability exists due to input validation error when processing untrusted input in applications that are using RegexRequestMatcher with `.` in the regular expression. A remote non-authenticated attacker can bypass authorization checks.
