The Crimson 3.2 Windows-based configuration tool allows users with administrative access to define new passwords for users and to download the resulting security configuration to a device. If such a password contains the percent (%) character, invalid values will be included, potentially truncating the string if a NUL is encountered. If the simplified password is not detected by the administrator, the device might be left in a vulnerable state as a result of more-easily compromised credentials. Note that passwords entered via the Crimson system web server do not suffer from this vulnerability.
This vulnerability allows a potential attacker to exploit improperly configured passwords, leading to unauthorized access and manipulation of system settings. With a CVSS score of 8.8, it is essential for organizations utilizing this tool to recognize the risk and implement necessary patches or workarounds.
Risk to organizations includes the potential for unauthorized access to critical systems, especially if users fail to detect simplified passwords. Organizations should prioritize patching immediately.
The urgency for defenders is high, as exploitation could lead to significant integrity and availability impacts. Therefore, immediate action is warranted to secure the affected systems.
Vulnerability Details
The official CVE description states that the Crimson 3.2 Windows-based configuration tool allows users with administrative access to define new passwords for users. If a password contains the percent (%) character, it can lead to invalid values being processed, which may truncate the password string if a NUL character is encountered. This issue is particularly concerning, as it could leave the system vulnerable if such passwords are not promptly detected by administrators.
The vulnerability has been scored with a CVSS of 8.8, categorized as high severity. This indicates that the vulnerability is exploitable with relatively low complexity and no privileges required, making it a significant risk for organizations using the affected product.
The affected product is the Crimson software by RedLion, specifically version 3.2 and prior builds. The vulnerability was published on November 6, 2023, and is classified under CWE-158.
Technical Analysis
The root cause of this vulnerability lies in how the Crimson tool processes passwords. When users create passwords that include the percent (%) character, the software may inadvertently truncate the password string, resulting in a simplified version that is easier to compromise. This is compounded by the fact that no user interaction is required to exploit this issue once the password is set.
The attack vector is network-based, with low attack complexity. No privileges are required to exploit the vulnerability, and it does not necessitate user interaction, making it particularly dangerous. The impacts of this vulnerability are severe, affecting confidentiality, integrity, and availability.
Risk & Impact Analysis
Real-world deployment of the Crimson configuration tool could expose organizations to significant risks due to this vulnerability. If compromised credentials are utilized, attackers may gain unauthorized access to critical systems, potentially leading to further exploits within the network.
The blast radius of such an attack could be extensive, particularly in environments where the Crimson tool integrates with other critical systems. Therefore, organizations should assess their exposure and prioritize remediation efforts based on the CVSS score and the potential impact of exploitation.
Given the high CVSS score and the absence of known exploits in the wild, organizations should address this vulnerability in their priority patch cycle to mitigate risks effectively.
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of the Crimson configuration tool include all versions prior to the vendor patch, specifically version 3.2 and its various builds, including but not limited to builds 3.2.0008.0 through 3.2.0053.18.
Mitigation & Remediation
Organizations should prioritize patching immediately to remediate this vulnerability. The vendor, RedLion, has provided updates that address this issue. Ensure you upgrade to the latest version as specified by the vendor's advisory. Additionally, consider implementing configuration hardening to mitigate risks further.
For ongoing security, organizations may also benefit from conducting regular security assessments, including penetration testing to identify similar weaknesses across their systems.
Detection Guidance
To detect potential exploitation of this vulnerability, security teams should monitor logs for any unusual password creation attempts, particularly those involving special characters like the percent (%) symbol. Additionally, behavioral anomalies in user access patterns should be closely watched.
AppSecure Threat Intelligence Insight
The long-term significance of this vulnerability indicates a need for heightened security awareness regarding configuration management tools. It underscores the importance of implementing robust password policies that preclude the use of special characters that could lead to vulnerabilities.
Security teams should learn from this incident and ensure that they regularly review and update their security configurations to mitigate similar vulnerabilities in the future. Additionally, they should consider adopting vulnerability management programs as part of their overall security strategy.
In conclusion, organizations must remain vigilant in monitoring and addressing vulnerabilities, employing a proactive approach to security that includes regular assessments and timely updates.
