CVE-2011-1923 describes a vulnerability in the Diffie-Hellman key-exchange implementation within PolarSSL before version 0.14.2. Specifically, the dhm.c file fails to properly validate a public parameter, making it susceptible to man-in-the-middle (MitM) attacks. This flaw allows attackers to more easily obtain the shared secret key by modifying network traffic, similar to CVE-2011-5095. With a CVSS score of 4.0 (AV:N/AC:H/Au:N/C:P/I:P/A:N), it indicates a network-based attack with high complexity, leading to partial confidentiality and integrity impact. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage for this vulnerability.
