CVE-2025-52969: ClickHouse 25.7.1.557 allows low-privileged users to execute shell commands by querying existing Executable() tables created by higher-privileged users. Although the CREATE TABLE privilege is restricted, there is no access control preventing low-privileged users from invoking Executable tables already present in the system. If an attacker can influence the contents of the script referenced by the Executable() engine through writable paths, they may execute controlled commands in the context of the ClickHouse server, leading to privilege escalation and unauthorized code execution. NOTE: the Supplier's position is that these types of executions by low-privileged users are the expected behavior.
The exploitability of CVE-2025-52969 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
This vulnerability, CVE-2025-52969, requires a high level of attack complexity and low privileges, making it difficult but not impossible to exploit. Organizations should ensure robust security configurations to mitigate risks.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2025-52969, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2025-52969, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
