Description

This security bulletin contains information about 4 vulnerabilities.


1) Path traversal (CVE-ID: CVE-2022-30333)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

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


The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error when processing directory traversal sequences when extracting files from archive. A remote attacker can create a specially crafted archive and overwrite arbitrary files on the system with privileges of the current user.

The vulnerability affects Linux and UNIX systems.


2) Improper input validation (CVE-ID: CVE-2022-48579)

CWE-ID: CWE-20 - Improper input validation

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


The vulnerability allows a local non-authenticated attacker to gain access to sensitive information.

The vulnerability exists due to improper input validation within the Outside In Core (unrar) component in Oracle Outside In Technology. A local non-authenticated attacker can exploit this vulnerability to gain access to sensitive information.


3) Improper Validation of Array Index (CVE-ID: CVE-2023-40477)

CWE-ID: CWE-129 - Improper Validation of Array Index

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


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

The vulnerability exists due to improper validation of array index when processing recovery volumes. A remote attacker can trick the victim to open a specially crafted archive and execute arbitrary code on the system.


4) Input validation error (CVE-ID: CVE-2024-33899)

CWE-ID: CWE-20 - Improper input validation

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


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

The vulnerability exists due to insufficient validation of ANSI escape sequences within the CLI interface. A remote attacker can pass specially crafted input via CLI and spoof the archive output or perform a denial of service (DoS) attack.

Note, the vulnerability affects Linux and Unix installations only.
