CVE-2023-46741
CWE-200Published: January 3, 2024· Updated: Jun 17, 2026
Official Description
CubeFS is an open-source cloud-native file storage system. A vulnerability was found in CubeFS prior to version 3.3.1 that could allow users to read sensitive data from the logs which could allow them escalate privileges. CubeFS leaks configuration keys in plaintext format in the logs. These keys could allow anyone to carry out operations on blobs that they otherwise do not have permissions for. For example, an attacker that has succesfully retrieved a secret key from the logs can delete blogs from the blob store. The attacker can either be an internal user with limited privileges to read the log, or they can be an external user who has escalated privileges sufficiently to access the logs. The vulnerability has been patched in v3.3.1. There is no other mitigation than upgrading.
Risk Analysis
CubeFS leaks configuration keys in plaintext within its logs, allowing unauthorized users to gain access to sensitive data. This critical vulnerability allows attackers to escalate privileges and perform unauthorized operations on blobs, such as deletion. The high CVSS score reflects the potential for full compromise of confidentiality, integrity, and availability.
There is no known public exploit for this vulnerability, and it is not currently listed in the CISA KEV catalog. It is remotely exploitable due to the network-based attack vector.
Users must upgrade to CubeFS version 3.3.1 or later to resolve this issue. No other mitigation is available.
Technical Analysis
CVE-2023-46741 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
From a weakness classification perspective (CWE-200): Information exposure vulnerabilities leak sensitive data to unauthorized actors.
