CVE-2023-29054
Siemens SCALANCE SSH Weak Ciphers Vulnerability (Man-in-the-Middle)
Description

A vulnerability has been identified in SCALANCE X200-4P IRT (All versions < V5.5.2), SCALANCE X201-3P IRT (All versions < V5.5.2), SCALANCE X201-3P IRT PRO (All versions < V5.5.2), SCALANCE X202-2IRT (All versions < V5.5.2), SCALANCE X202-2IRT (All versions < V5.5.2), SCALANCE X202-2P IRT (All versions < V5.5.2), SCALANCE X202-2P IRT PRO (All versions < V5.5.2), SCALANCE X204IRT (All versions < V5.5.2), SCALANCE X204IRT (All versions < V5.5.2), SCALANCE X204IRT PRO (All versions < V5.5.2), SCALANCE XF201-3P IRT (All versions < V5.5.2), SCALANCE XF202-2P IRT (All versions < V5.5.2), SCALANCE XF204-2BA IRT (All versions < V5.5.2), SCALANCE XF204IRT (All versions < V5.5.2), SIPLUS NET SCALANCE X202-2P IRT (All versions < V5.5.2). The SSH server on affected devices is configured to offer weak ciphers by default. This could allow an unauthorized attacker in a man-in-the-middle position to read and modify any data passed over the connection between legitimate clients and the affected device.
