Vulnerability Details
The vulnerability CVE-2022-2125 is classified as a heap-based buffer overflow in the GitHub repository vim/vim, affecting versions prior to 8.2. This vulnerability can be exploited locally, requiring user interaction, and has been scored with a CVSS 3.1 base score of 7.8, indicating a high severity level.
The affected products include vim, Fedora, and macOS. The vulnerability was published on June 19, 2022, and it has been assigned two Common Weakness Enumeration (CWE) identifiers: CWE-122 (Heap-based Buffer Overflow) and CWE-787 (Out-of-bounds Write).
Technical Analysis
The root cause of CVE-2022-2125 is a programming error that leads to heap-based buffer overflow conditions. Attackers may leverage this vulnerability by providing specially crafted input that exceeds the buffer capacity, potentially allowing for arbitrary code execution or other adverse effects.
The attack vector for this vulnerability is local, meaning that the attacker must have access to the target system. The attack complexity is rated as low, and no privileges are required to exploit this vulnerability. However, user interaction is necessary, as the attacker must convince the user to execute the malicious payload.
The impact on confidentiality, integrity, and availability is rated high, as successful exploitation could lead to complete control over the affected system, allowing attackers to manipulate sensitive data and disrupt services.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2022-2125 is substantial. Organizations using affected versions of Vim, macOS, or Fedora are at risk of potential exploitation if they do not address this vulnerability promptly. The blast radius could be significant, especially in environments where critical applications or sensitive data are managed.
Given the CVSS score of 7.8, organizations should address this vulnerability in their priority patch cycle. The potential impact on business operations, data security, and compliance requirements necessitates immediate attention and remediation efforts.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The vulnerability affects all versions of Vim prior to 8.2, as well as specific versions of Fedora (35 and 36) and macOS (versions prior to 11.7 and 12.0 to 12.6).
Mitigation & Remediation
Organizations are advised to apply the latest patches provided by the vendors. Users of Vim should upgrade to version 8.2.5122 or later, and macOS users should update to the latest available version.
