Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A vulnerability has been identified in Cerberus PRO EN Engineering Tool (All versions < IP8), Cerberus PRO EN Fire Panel FC72x IP6 (All versions < IP6 SR3), Cerberus PRO EN Fire Panel FC72x IP7 (All versions < IP7 SR5), Cerberus PRO EN X200 Cloud Distribution IP7 (All versions < V3.0.6602), Cerberus PRO EN X200 Cloud Distribution IP8 (All versions < V4.0.5016), Cerberus PRO EN X300 Cloud Distribution IP7 (All versions < V3.2.6601), Cerberus PRO EN X300 Cloud Distribution IP8 (All versions < V4.2.5015), Cerberus PRO UL Compact Panel FC922/924 (All versions < MP4), Cerberus PRO UL Engineering Tool (All versions < MP4), Cerberus PRO UL X300 Cloud Distribution (All versions < V4.3.0001), Desigo Fire Safety UL Compact Panel FC2025/2050 (All versions < MP4), Desigo Fire Safety UL Engineering Tool (All versions < MP4), Desigo Fire Safety UL X300 Cloud Distribution (All versions < V4.3.0001), Sinteso FS20 EN Engineering Tool (All versions < MP8), Sinteso FS20 EN Fire Panel FC20 MP6 (All versions < MP6 SR3), Sinteso FS20 EN Fire Panel FC20 MP7 (All versions < MP7 SR5), Sinteso FS20 EN X200 Cloud Distribution MP7 (All versions < V3.0.6602), Sinteso FS20 EN X200 Cloud Distribution MP8 (All versions < V4.0.5016), Sinteso FS20 EN X300 Cloud Distribution MP7 (All versions < V3.2.6601), Sinteso FS20 EN X300 Cloud Distribution MP8 (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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis
How this class of weakness works · CWE-120

A fixed-size buffer is filled without checking the length of the incoming data, so it overflows into neighbouring memory. This is the classic overflow attackers use to overwrite return addresses and hijack execution. The fix is strict length checks and safe, bounded string and memory functions.

General guidance for the classic buffer overflow class — the official description and references above are authoritative for this specific CVE. Want a bespoke review and a reviewed fix? Ask our team →
