Embedded Malicious Code
CWE-506
The product contains code that appears to be malicious in nature.
We track 48 vulnerabilities of this type. 100% are rated high or critical, and the average CVSS score is 9.3. 9 have been exploited in real attacks.
How this weakness is prevented
- Implementation Operation: Remove the malicious code and start an effort to ensure that no more malicious code exists. This may require a detailed review of all code, as it is possible to hide a serious attack in only one or two lines of code. These lines may be located almost anywhere in an application and may have been intentionally obfuscated by the attacker.
