Weakness (CWE)
CWE-506: Embedded Malicious Code
The product contains code that appears to be malicious in nature.
How to prevent it (1 mitigation)
-
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.
