CVE-2025-22237 is a vulnerability affecting VMware SALT versions 3006.x and 3007.x. The flaw resides in the 'on demand' pillar functionality of SALT, which is a configuration management and orchestration tool used to manage infrastructure at scale. Specifically, an attacker who already possesses access to a minion key—a credential used by SALT minions to authenticate with the master—can exploit this vulnerability by supplying a specially crafted Git URL. This crafted URL triggers the execution of arbitrary commands on the SALT master server with the same privileges as the master process itself. Given that the master process typically runs with elevated privileges to manage and control minions, this can lead to a full compromise of the master server. The attack vector requires local access to a minion key, which implies that the attacker must have some level of prior access or insider capability. The CVSS 3.1 score is 6.7 (medium severity), with the vector indicating local attack vector (AV:L), low attack complexity (AC:L), high privileges required (PR:H), no user interaction (UI:N), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No known exploits are currently reported in the wild, and no patches or mitigation links have been published at the time of this report. The vulnerability was reserved in early 2025 and published in June 2025. This vulnerability highlights a critical risk in the trust model of SALT's authentication and pillar data retrieval mechanisms, where misuse of the Git URL input can escalate privileges and execute arbitrary commands on the master server, potentially leading to full system compromise and lateral movement within the network infrastructure managed by SALT.

For European organizations, the impact of this vulnerability can be significant, especially for enterprises and service providers relying on VMware SALT for infrastructure automation and configuration management. A successful exploitation could lead to complete compromise of the SALT master server, enabling attackers to execute arbitrary commands with elevated privileges. This can result in unauthorized access to sensitive configuration data, disruption of automated management processes, and potential deployment of malicious configurations across the managed infrastructure. The confidentiality, integrity, and availability of critical systems could be severely affected, leading to data breaches, service outages, and operational disruptions. Given that SALT is often used in cloud environments, data centers, and hybrid infrastructures, the ripple effect of such a compromise could extend to multiple systems and services. Additionally, the requirement for possession of a minion key means that insider threats or attackers who have already breached lower-tier systems could escalate their privileges rapidly. For sectors such as finance, healthcare, telecommunications, and critical infrastructure within Europe, this vulnerability poses a tangible risk to operational continuity and data protection compliance under regulations like GDPR.

To mitigate this vulnerability, European organizations should take the following specific actions beyond generic patching advice: 1) Immediately audit and inventory all SALT minion keys in use, ensuring that only authorized personnel and systems have access. 2) Implement strict access controls and monitoring around the storage and usage of minion keys to prevent unauthorized access or theft. 3) Restrict or disable the 'on demand' pillar functionality if it is not essential to operational workflows, thereby reducing the attack surface. 4) Employ network segmentation to isolate SALT master servers from less trusted network zones and limit lateral movement opportunities. 5) Monitor logs and network traffic for unusual Git URL requests or unexpected command executions originating from minions. 6) Enforce the principle of least privilege on the SALT master process where feasible, potentially running it with reduced privileges or within a hardened containerized environment. 7) Prepare incident response plans specifically addressing potential SALT master compromises, including rapid key revocation and master server restoration procedures. 8) Engage with VMware support and subscribe to their security advisories to receive timely updates and patches once available. These measures will help reduce the risk of exploitation and limit the impact if an attacker gains access to a minion key.
