AI Insight
LLM-synthesized narrative grounded in this CVE's description and references.
CodeMeter prior to v6.81 crashes when processing a crafted license file due to unverified length fields, enabling remote denial-of-service without authentication.
Vulnerability
In CodeMeter Runtime versions prior to 6.81, the packet parser mechanism does not verify length fields, leading to a buffer access with incorrect length value (CWE-805). A specially crafted license file triggers this flaw when parsed, causing the application to crash. All versions prior to 6.81 are affected [1].
Exploitation
An unauthenticated attacker can exploit this vulnerability remotely with low complexity and no user interaction. By sending a malicious license file to the CodeMeter service (or to an application using CodeMeter), the vulnerable packet parser processes the crafted input, directly triggering the crash without any special privileges or access [1].
Impact
Successful exploitation causes a denial-of-service condition: CodeMeter and any third-party software depending on it will terminate abnormally. The advisory notes that for this specific CVE the outcome is a crash; other related CVEs cover remote code execution or heap data disclosure [1].
Mitigation
Wibu-Systems fixed CVE-2020-14513 in CodeMeter Runtime version 6.81. Users should update to 6.81 or later immediately. No workarounds have been published [1].
