CVE-2022-44622 is a vulnerability identified in JetBrains TeamCity, a widely used continuous integration and continuous deployment (CI/CD) server, specifically affecting versions from 2021.2 through 2022.10. The issue stems from improper access control (CWE-284) related to secure token health items within the application. In these affected versions, the access permissions granted to users for these secure token health items were overly permissive, allowing users with certain privileges to access information or functionality beyond their intended scope. The vulnerability does not allow for privilege escalation or direct compromise of system integrity or availability but does expose confidential information related to secure tokens, which could potentially be leveraged in further attacks. The CVSS v3.1 base score is 2.7, indicating a low severity level, with the vector string CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N. This means the vulnerability can be exploited remotely over the network (AV:N) with low attack complexity (AC:L), but requires high privileges (PR:H) and no user interaction (UI:N). The impact is limited to confidentiality (C:L) with no impact on integrity or availability. No known exploits have been reported in the wild, and JetBrains has not yet published specific patches addressing this issue as of the provided data. The vulnerability was publicly disclosed on November 3, 2022, and is recognized by CISA as an enriched threat. Given the nature of TeamCity as a CI/CD tool, exposure of secure token health information could aid attackers in reconnaissance or lateral movement within development environments if combined with other vulnerabilities or insider threats.

For European organizations, the impact of CVE-2022-44622 is primarily related to the confidentiality of secure token information within TeamCity environments. Organizations relying on TeamCity for their software development pipelines could face risks where privileged users or compromised accounts with high privileges gain access to sensitive token health data. While this does not directly affect system integrity or availability, the leakage of token information could facilitate unauthorized access to other systems or services integrated with TeamCity, potentially leading to further compromise. This is particularly critical for organizations with complex DevOps environments or those handling sensitive data, such as financial institutions, healthcare providers, and critical infrastructure operators. The low CVSS score reflects limited immediate risk, but the potential for chained attacks or insider misuse means that organizations should not ignore this vulnerability. Additionally, the lack of known exploits reduces the immediate threat but does not eliminate the risk of targeted attacks or future exploit development.

1. Restrict high-privilege accounts: Limit the number of users with high privileges in TeamCity to the minimum necessary and enforce strict access controls and monitoring on these accounts. 2. Audit and monitor access: Implement detailed logging and monitoring of access to secure token health items and related sensitive areas within TeamCity to detect any unauthorized or suspicious activity. 3. Network segmentation: Isolate TeamCity servers within secure network segments to reduce exposure to external threats and limit lateral movement possibilities. 4. Update and patch management: Although no specific patches are listed, regularly check JetBrains’ official channels for updates or patches addressing this vulnerability and apply them promptly. 5. Use token rotation and revocation: Regularly rotate secure tokens and revoke any tokens that may have been exposed or are no longer needed to minimize the risk of misuse. 6. Implement multi-factor authentication (MFA): Enforce MFA for all high-privilege TeamCity accounts to reduce the risk of credential compromise. 7. Conduct internal security reviews: Periodically review TeamCity configurations and permissions to ensure that access controls align with the principle of least privilege and that no excessive permissions exist.
