SICAM SIAPP SDK V<2.1.7 Server Stack Overflow via Oversized Input (DOS)
CVE-2026-25572 Published on March 10, 2026
A vulnerability has been identified in SICAM SIAPP SDK (All versions < V2.1.7). The SICAM SIAPP SDK server component does not enforce maximum length checks on certain variables before use. This could allow an attacker to send an oversized input that could trigger a stack overflow crashing the process and potentially causing denial of service.
Weakness Type
What is a length manipulation Vulnerability?
The software parses a formatted message or structure, but it does not handle or incorrectly handles a length field that is inconsistent with the actual length of the associated data. If an attacker can manipulate the length parameter associated with an input such that it is inconsistent with the actual length of the input, this can be leveraged to cause the target application to behave in unexpected, and possibly, malicious ways. One of the possible motives for doing so is to pass in arbitrarily large input to the application. Another possible motivation is the modification of application state by including invalid data for subsequent properties of the application. Such weaknesses commonly lead to attacks such as buffer overflows and execution of arbitrary code.
CVE-2026-25572 has been classified to as a length manipulation vulnerability or weakness.
