VAR-201309-0004
Vulnerability from variot - Updated: 2023-12-18 12:30The Board Management Controller (BMC) in the Serial over LAN (SoL) subsystem in Cisco Unified Computing System (UCS) relies on a hardcoded private key, which allows man-in-the-middle attackers to obtain sensitive information or modify the data stream by leveraging knowledge of this key, aka Bug ID CSCte90338. Vendors have confirmed this vulnerability Bug ID CSCte90338 It is released as.Man-in-the-middle attacks (man-in-the-middle attack) By using hard-coded key information, important information may be obtained or the data stream may be changed. Cisco Unified Computing System is prone to an information-disclosure vulnerability in the implementation of Serial over LAN (SoL). Attackers can exploit this issue to obtain the private key and use it to decrypt traffic between end user and affected system. Successfully exploiting this issue allows attackers to view or modify Serial over LAN (SoL) communications by performing man-in-the-middle attacks. This issue is tracked by Cisco Bug ID CSCte90338. Cisco Unified Computing System (UCS) is a unified computing system of Cisco (Cisco). The system integrates network, computing and virtualization resources into one platform by extensively adopting virtualization technology
