Overview
CVE-2025-63206 details an authentication bypass vulnerability discovered in the web-based interface of the Dasan Switch DS2924. This vulnerability affects firmware versions 1.01.18 and 1.02.00. Attackers can exploit this flaw to gain escalated privileges by crafting and storing malicious cookies within the web browser. This could potentially allow unauthorized access to sensitive network configurations and data.
Technical Details
The vulnerability stems from insufficient validation of cookie data within the Dasan Switch DS2924’s web interface. An attacker can manipulate the cookie values to bypass authentication checks and gain elevated privileges. By crafting specific cookie values that the system interprets as legitimate administrator credentials, an attacker can effectively gain control of the switch’s management interface. The vulnerability is triggered during the cookie processing stage of the web application. Further details, including proof of concept exploits, are available in the provided references.
CVSS Analysis
The CVSS score for CVE-2025-63206 is currently listed as N/A. This means that the severity level and associated metrics have not yet been officially calculated. However, given the potential for complete system compromise due to an authentication bypass, it is likely to be rated as a High or Critical severity vulnerability once a CVSS score is assigned.
Possible Impact
Successful exploitation of CVE-2025-63206 can have significant consequences:
- Complete System Compromise: Attackers can gain full administrative control over the affected Dasan Switch DS2924.
- Network Disruption: Unauthorized access could be used to modify network configurations, leading to network outages or performance degradation.
- Data Theft: Attackers could potentially access sensitive data passing through the switch.
- Malware Deployment: The compromised switch could be used as a staging point for further attacks within the network.
Mitigation and Patch Steps
Currently, the primary mitigation strategy is to:
- Upgrade Firmware (If Available): Check the Dasan SMC website for updated firmware that addresses this vulnerability. This is the most effective solution.
- Monitor Network Traffic: Implement network intrusion detection systems (IDS) to monitor for suspicious activity related to the Dasan Switch DS2924.
- Restrict Access: Limit access to the switch’s management interface to only authorized personnel and trusted networks.
- Implement Strong Password Policies: Enforce strong and unique passwords for all user accounts on the switch.
