The CVE-2022-25865 vulnerability affects Microsoft Workspace Tools versions before 0.18.4. This vulnerability allows for command injection via git argument injection, specifically within the function fetchRemoteBranch(remote: string, remoteBranch: string, cwd: string). The parameters remote and remoteBranch are passed directly to the git fetch subcommand, allowing attackers to set additional flags that can be manipulated for command injection.
This vulnerability has been classified with a CVSS score of 8.1, indicating a high severity level. It poses a significant risk to organizations relying on these tools, as successful exploitation could result in unauthorized command execution, potentially compromising sensitive data.
Organizations should prioritize patching immediately to mitigate this vulnerability. The risks associated with command injection can lead to severe implications, including data breaches and system compromises.
Currently, there are no known public exploits or proof of concept (PoC) available for this vulnerability. However, the high potential for exploitation necessitates immediate attention from security teams.
Vulnerability Details
The official description states that the package workspace-tools before version 0.18.4 is vulnerable to command injection via git argument injection. The relevant CVSS vector is CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H, indicating a network attack vector with high complexity, no privileges required, and no user interaction needed. The impacts on confidentiality, integrity, and availability are all rated as high.
The vulnerability has been assigned to CWE-88, which relates to improper argument injection. It was published on May 13, 2022, and has since been marked as modified due to updates in the understanding of its implications.
Technical Analysis
The root cause of this vulnerability stems from improper handling of input parameters in the fetchRemoteBranch function. By injecting malicious arguments, an attacker could manipulate the git fetch command to execute arbitrary commands on the host system.
The attack vector is network-based, requiring no privileges or user interaction, making it particularly dangerous. The attack complexity is rated as high, indicating that while the exploit may be sophisticated, it is feasible given the right circumstances.
The potential impacts of this vulnerability are severe, affecting confidentiality, integrity, and availability of the system. An attacker could gain unauthorized access to sensitive information, modify data, or disrupt service availability.
Risk & Impact Analysis
Risk to organizations includes the potential for unauthorized command execution, which could lead to significant data breaches and system integrity issues. The blast radius of this vulnerability is considerable, given the widespread use of the affected Microsoft Workspace Tools package.
Organizations should assess their exposure and prioritize remediation based on the CVSS score, which indicates a high level of urgency for patching this vulnerability. The potential for exploitation is high, especially in environments where the affected tools are utilized extensively.
