In JetBrains TeamCity, a critical vulnerability (CVE-2024-23917) has been identified that allows for authentication bypass leading to remote code execution (RCE). This vulnerability affects all versions prior to 2023.11.3 and has been assigned a CVSS score of 9.8, indicating a critical severity level. The implications of this vulnerability are significant, as it enables unauthorized access to sensitive systems, potentially leading to full compromise.
Risk to organizations includes unauthorized access to data and systems, which could be exploited by attackers to execute arbitrary code. Given the high CVSS score, organizations using JetBrains TeamCity must address this vulnerability with urgency. Patching should be prioritized immediately to prevent potential exploitation.
Currently, there are no known exploits for this vulnerability, but the lack of a public proof of concept (PoC) or exploit does not diminish the critical nature of the threat. Organizations should remain vigilant and ensure they are running an updated version of TeamCity.
Organizations using JetBrains TeamCity should take immediate action to patch to version 2023.11.3 or later to mitigate this critical vulnerability. The potential consequences of inaction could lead to severe breaches and data loss.
Vulnerability Details
The vulnerability allows for authentication bypass, which can lead to remote code execution (RCE). This issue primarily affects JetBrains TeamCity versions before 2023.11.3. The CVSS score of 9.8 denotes a critical risk, with high impacts on confidentiality, integrity, and availability.
The vulnerability is classified under CWE-288 (Authentication Bypass) and CWE-306 (Missing Authentication for Critical Function). These classifications highlight the failure to properly enforce authentication measures, leading to unauthorized access.
Technical Analysis
The root cause of this vulnerability stems from improper authentication mechanisms within JetBrains TeamCity. The attack vector is identified as network, with low attack complexity, meaning that an attacker with network access can exploit this vulnerability without needing extensive technical skills.
No privileges are required to exploit this vulnerability, and user interaction is not necessary. The impact on confidentiality, integrity, and availability is rated as high, indicating severe risks to the affected systems.
Risk & Impact Analysis
The risk posed by this vulnerability is substantial, as it allows attackers to gain unauthorized access to sensitive information and systems. The potential blast radius includes all users and systems connected to JetBrains TeamCity. Organizations must evaluate their exposure and implement necessary security measures.
Given the CVSS score of 9.8, organizations should prioritize remediation efforts immediately. The urgency of this vulnerability necessitates swift action to mitigate the risk of exploitation, which, although currently not known to have been exploited, remains a critical concern.
