CVE-2025-32462 is a vulnerability found in sudo, specifically affecting versions prior to 1.9.17p1. This vulnerability allows listed users to execute commands on unintended machines when a sudoers file specifies a host that is neither the current host nor ALL. With a CVSS score of 2.8, this vulnerability is classified as low severity, but it still poses a risk to systems where sudo is improperly configured.
Although the severity is low, organizations should recognize that risk to organizations includes unauthorized command execution, which can lead to further exploitation or manipulation of systems. The presence of an exploit indicates that attackers may leverage this vulnerability if not adequately addressed. Therefore, organizations should prioritize patching immediately.
The vulnerability was published on June 30, 2025, and is categorized under CWE-863. Given its nature and potential impact, it is crucial for organizations to take it seriously, especially in environments using sudo for privilege management.
Organizations using affected versions of sudo should schedule remediation as part of their priority patch cycle. They must evaluate their sudoers configuration to mitigate the risk associated with this vulnerability.
Vulnerability Details
The official description states that "Sudo before 1.9.17p1, when used with a sudoers file that specifies a host that is neither the current host nor ALL, allows listed users to execute commands on unintended machines." This indicates a misconfiguration scenario where users may gain access to systems beyond their intended scope.
The CVSS score of 2.8 indicates a low severity. The attack vector is local, with a high attack complexity and low privileges required. There is no user interaction necessary, and the vulnerability impacts confidentiality minimally, with low integrity impact.
Organizations are encouraged to review their sudo configurations and apply updates to mitigate this vulnerability. The potential for privilege escalation through misconfigured sudoers files must not be overlooked.
Technical Analysis
The root cause of CVE-2025-32462 relates to the improper configuration of sudoers files that specify host rules incorrectly. This misconfiguration can lead to unintended command execution on machines that should not be accessible to specified users.
The attack vector is local, meaning that an attacker must have local access to the system. Attack complexity is classified as high, indicating that a potential attacker would need to understand the configuration intricacies of the sudoers file to exploit this vulnerability effectively. Privileges required are low, meaning that even users with minimal rights could leverage this vulnerability if the sudoers file is misconfigured.
Additionally, this vulnerability does not require any user interaction, making it more dangerous as it can be exploited without the user being aware. Confidentiality impact is none, while integrity impact is low, as it could allow unauthorized command execution that may alter system state.
Organizations should enhance monitoring of sudo access and configurations to swiftly detect any misuse or misconfigurations that could lead to exploitation.
Risk & Impact Analysis
The real-world deployment risk of CVE-2025-32462 lies in the potential unauthorized access to systems that should be secured against such access. With the ability for listed users to execute commands on unintended machines, the blast radius can extend beyond initial access points, potentially impacting sensitive data or system integrity.
Given the low severity score, organizations may perceive this vulnerability as a lower priority. However, organizations should address it in their routine maintenance to prevent any exploitation that could lead to more severe consequences.
The urgency of addressing this vulnerability is moderate, as it can be exploited but requires a specific configuration. Organizations should schedule remediation to ensure that their sudo configurations do not lead to unintended access.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | Yes |
Public PoC | Yes |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of sudo include all versions prior to 1.9.17. Organizations should ensure they upgrade to the latest version to eliminate this vulnerability.
Mitigation & Remediation
Organizations should apply the latest patches for sudo to mitigate this issue. If a patch is unavailable, they should review the sudoers configuration carefully to ensure that no unauthorized commands can be executed on unintended machines. Implementing strict access controls and using minimal privilege principles can help reduce the risk.
For more information on securing your systems against such vulnerabilities, organizations should consider engaging in penetration testing to identify potential weaknesses.
Detection Guidance
Organizations should monitor their logs for unusual sudo access patterns or commands executed outside of expected parameters. Behavioral anomalies in user command execution can also indicate potential exploitation attempts. Network signatures that detect unauthorized access attempts can be valuable for detection.
