CVE-2022-2285 is a high-severity vulnerability identified in the Vim text editor, specifically impacting versions prior to 9.0. The vulnerability is classified as an integer overflow or wraparound issue, which could allow local attackers to manipulate the application in a way that may result in unauthorized access or data compromise. The CVSS score is rated at 7.8, indicating a significant risk to systems utilizing affected versions.
This vulnerability allows attackers to exploit the integer overflow condition through local access, necessitating user interaction to trigger the exploit. The potential impacts are severe, affecting confidentiality, integrity, and availability of the application. Therefore, organizations that use Vim should prioritize patching by updating to version 9.0 or later, as this will mitigate the identified risk.
The urgency for defenders is high, given that a known exploit exists. Organizations must take immediate action to secure their environments and ensure that they are operating on patched versions of the software.
Failure to address this vulnerability could lead to significant data breaches and exploitation, emphasizing the need for a robust vulnerability management process.
Vulnerability Details
The official description states that CVE-2022-2285 is an integer overflow or wraparound in the GitHub repository for Vim prior to version 9.0. The vulnerability is classified under CWE-190, indicating the specific nature of the flaw. The CVSS version used for scoring is 3.1, with the following vector: CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H.
The vulnerability affects several products, including Vim and various Linux distributions like Debian and Fedora. Specifically, the vulnerable configurations include any version of Vim prior to 9.0.0018, Fedora versions 35 and 36, and Debian Linux version 10.0.
Technical Analysis
The root cause of CVE-2022-2285 stems from an integer overflow that can occur when handling certain operations within Vim. The attack vector is local, meaning an attacker must have access to the system where Vim is installed. The complexity of the attack is low, as it requires no prior authentication or permissions. However, user interaction is necessary to trigger the exploit.
The implications of this vulnerability are significant. Confidentiality, integrity, and availability impacts are all rated high, meaning that successful exploitation could lead to unauthorized access to sensitive data, alteration of files, or even denial of service conditions.
Risk & Impact Analysis
Organizations using Vim or its derivatives face a considerable risk due to this vulnerability. The potential for data breaches is high, particularly in local environments where attackers may have physical access. The blast radius extends to critical systems that rely on Vim, making it essential for organizations to assess their exposure and act promptly.
Given the CVSS score of 7.8, organizations should address this vulnerability in their priority patch cycle. The presence of a known exploit further emphasizes the urgency of remediation.

|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of Vim include all versions prior to 9.0.0018. Additionally, Fedora versions 35 and 36, as well as Debian Linux version 10.0, are also vulnerable to this issue. Organizations should ensure that they have upgraded to the latest versions to mitigate the risk.
Mitigation & Remediation
To mitigate the risks associated with CVE-2022-2285, organizations must prioritize patching Vim to the latest version, which is 9.0 or later. If immediate patching is not possible, consider implementing workarounds such as restricting access to the Vim application and monitoring for suspicious activity.
Configuration hardening is also recommended, including disabling features that may exacerbate the vulnerability. Enhanced network controls can help limit exposure, while continuous monitoring of logs for anomalous behavior will assist in early detection of potential exploits.
