Detailsinfo

A vulnerability was found in Siemens Cerberus PRO EN Engineering Tool, Cerberus PRO EN Fire Panel FC72x, Cerberus PRO EN X200 Cloud Distribution, Cerberus PRO EN X300 Cloud Distribution, Sinteso FS20 EN Engineering Tool, Sinteso FS20 EN Fire Panel FC20, Sinteso FS20 EN X200 Cloud Distribution, Sinteso FS20 EN X300 Cloud Distribution and Sinteso Mobile (Cloud Software). It has been declared as very critical. Affected by this vulnerability is an unknown code block of the component X.509 Certificate Handler. The manipulation with an unknown input leads to a stack-based overflow vulnerability. The CWE definition for the vulnerability is CWE-121. A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function). As an impact it is known to affect confidentiality, integrity, and availability. The summary by CVE is:

A vulnerability has been identified in Cerberus PRO EN Engineering Tool (All versions < IP8), Cerberus PRO EN Fire Panel FC72x (All versions < IP8), Cerberus PRO EN X200 Cloud Distribution (All versions < V4.0.5016), Cerberus PRO EN X300 Cloud Distribution (All versions < V4.2.5015), Sinteso FS20 EN Engineering Tool (All versions < MP8), Sinteso FS20 EN Fire Panel FC20 (All versions < MP8), Sinteso FS20 EN X200 Cloud Distribution (All versions < V4.0.5016), Sinteso FS20 EN X300 Cloud Distribution (All versions < V4.2.5015), Sinteso Mobile (All versions < V3.0.0). The network communication library in affected systems does not validate the length of certain X.509 certificate attributes which might result in a stack-based buffer overflow. This could allow an unauthenticated remote attacker to execute code on the underlying operating system with root privileges.

The weakness was released 03/12/2024 as ssa-225840. It is possible to read the advisory at cert-portal.siemens.com. This vulnerability is known as CVE-2024-22039 since 01/04/2024. The technical details are unknown and an exploit is not publicly available. The pricing for an exploit might be around USD $5k-$25k at the moment (estimation calculated on 03/12/2024).
