Brocade SANnav prior to versions 2.2.0.2 and 2.1.1.8 exposes a vulnerability where the Fabric OS switch password is logged in plain text within the asyncjobscheduler-manager.log file. This vulnerability allows sensitive information to be compromised, presenting a real-world risk of unauthorized access to the affected systems.
With a CVSS score of 6.5, this vulnerability is classified as medium severity. The implications for organizations include high confidentiality impact, which could lead to unauthorized access to critical systems. Given the nature of the exposed information, organizations should prioritize patching this vulnerability immediately.
As of now, no public exploit has been confirmed for this vulnerability. However, the ease of exploitation and the potential for serious consequences necessitate an urgent response from security teams.
Organizations using Broadcom SANnav should assess their deployments and ensure they are updated to the latest versions to mitigate this risk.
Vulnerability Details
The vulnerability in question allows the Fabric OS switch password to be logged in plaintext in the asyncjobscheduler-manager.log file. This was reported for versions prior to Brocade SANvav v. 2.2.0.2 and Brocade SANanv v. 2.1.1.8. Its CVSS score is 6.5, indicating a medium severity level due to its network attack vector and low complexity.
The affected systems include various versions of the Broadcom SANnav software, which is crucial for managing Fibre Channel networks.
Technical Analysis
The root cause of this vulnerability lies in the logging configuration of the SANnav software, which improperly handles sensitive information. Attackers may leverage this weakness over a network, given the low attack complexity and the low privileges required for exploitation. User interaction is not necessary, thereby increasing the likelihood of successful attacks.
The confidentiality impact is rated high since the password exposure could allow unauthorized access to network resources, while integrity and availability impacts are rated as none.
Risk & Impact Analysis
Organizations using Broadcom SANnav face significant risks due to this vulnerability. The exposure of sensitive credentials in logs can lead to unauthorized access, potentially compromising critical infrastructure. The blast radius is considerable, as attackers could exploit this vulnerability to gain further access within the network.
Given the medium severity of this vulnerability, organizations should address it in their priority patch cycle. The potential for exploitation is compounded by the fact that no public exploit has been confirmed, but the risk remains substantial.
