CVE-2021-41293 is a high-severity vulnerability affecting ECOA BAS controllers. This vulnerability allows unauthenticated attackers to exploit a path traversal flaw, which can lead to arbitrary file disclosure on the affected device. The CVSS score of 7.5 indicates a significant risk, as attackers may leverage this vulnerability to gain access to sensitive system information and files. Organizations should prioritize patching immediately to mitigate the associated risks.
The vulnerability has been classified under CWE-22, indicating that it involves improper handling of paths for file access. Given the nature of this vulnerability, the potential impact could be severe, affecting the confidentiality of sensitive information stored on the device. As of now, there are no known public exploits, but the risk remains high due to the nature of the attack vector, which is network-based with low complexity.
Organizations using affected ECOA products should take immediate action to address this vulnerability. The urgency is heightened by the increasing number of attacks targeting similar issues in other systems. Remediation should be scheduled without delay to prevent unauthorized access to sensitive information.
In conclusion, CVE-2021-41293 represents a critical security issue for ECOA BAS controllers. Organizations must take proactive measures to mitigate this vulnerability to safeguard their systems and data.
Vulnerability Details
The ECOA BAS controller suffers from a path traversal vulnerability, causing arbitrary files disclosure. Using the specific POST parameter, unauthenticated attackers can remotely disclose arbitrary files on the affected device and disclose sensitive and system information.
The CVSS score is 7.5, which is classified as high severity. This indicates a significant risk to organizations, as the attack vector is network-based, with low complexity, and requires no user interaction or privileges.
Technical Analysis
The root cause of this vulnerability lies in improper validation of file paths, which allows attackers to manipulate the path to access sensitive files. The attack vector is through a network, and the attack complexity is low, meaning that it can be exploited easily without a high level of skill.
No privileges are required to exploit this vulnerability, and it does not require user interaction. The confidentiality impact is high, as attackers may gain access to sensitive information, while integrity and availability impacts are minimal.
Risk & Impact Analysis
Risk to organizations includes the potential exposure of sensitive data due to unauthorized file access. The blast radius is considerable as it can affect any organization utilizing the ECOA BAS controller without proper security measures. Based on the CVSS score and the fact that it is not listed in KEV, organizations should address this vulnerability in their priority patch cycle.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
