CVE-2023-38950 is a high-severity vulnerability identified in the ZKTeco BioTime software version 8.5.5. This vulnerability allows unauthenticated attackers to exploit a path traversal issue in the iclock API, enabling them to read arbitrary files by supplying a crafted payload. The CVSS score for this vulnerability is 7.5, indicating a high level of risk and urgency for organizations to address it.
The risk to organizations includes potential exposure of sensitive information contained within the files that can be accessed through this vulnerability. Attackers may leverage this flaw to gain unauthorized insights into system configurations or user data, thus posing a significant threat to the security posture of affected implementations.
Organizations should prioritize patching immediately by upgrading to version 9.0.120240617.19506 of ZKBioTime, where this vulnerability has been addressed. Prompt action is essential to mitigate the risk of exploitation, given the potential for unauthorized access to critical files.
As of now, there are no known public exploits for this vulnerability, but its presence in the Known Exploited Vulnerabilities catalog indicates a recognized risk that could be targeted by malicious actors. Organizations are encouraged to stay vigilant and monitor for any emerging threats related to this CVE.
Vulnerability Details
The vulnerability detailed in CVE-2023-38950 is classified as a path traversal vulnerability affecting the iclock API of ZKTeco BioTime v8.5.5. It is characterized by the ability of an unauthenticated attacker to read arbitrary files by supplying a crafted payload. The vulnerability has been assigned a CVSS score of 7.5, indicating a high severity level. This suggests that the attack vector is network-based, the complexity is low, and no privileges or user interaction are required for successful exploitation.
The vulnerability was documented on August 3, 2023, and affects all versions prior to the vendor patch, specifically version 9.0.120240617.19506. The associated Common Weakness Enumeration (CWE) for this vulnerability is CWE-22.
Technical Analysis
The root cause of CVE-2023-38950 stems from inadequate validation of user-supplied input, allowing attackers to manipulate the file paths and gain access to files outside the intended directory. The attack vector is network-based, meaning that an attacker can exploit this vulnerability remotely. The attack complexity is low, indicating that the conditions required to exploit this vulnerability are not difficult to satisfy.
No privileges are required to exploit this vulnerability, and user interaction is not necessary. The impact of this vulnerability includes a high potential for confidentiality compromise, as attackers can read sensitive files. There is no impact on integrity or availability.
Risk & Impact Analysis
The deployment of ZKTeco BioTime without addressing CVE-2023-38950 presents significant risks to organizations. Given the high CVSS score of 7.5, the urgency for remediation is critical. The potential blast radius is extensive, as the vulnerability allows access to arbitrary files, which could lead to exposure of sensitive data and system configurations.
Organizations using affected versions should assess their risk based on their operational context and data sensitivity. The high-impact nature of this vulnerability, combined with its presence in the KEV catalog, emphasizes the need for immediate action to prevent unauthorized access and potential data breaches.
