Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-190: Integer Overflow or Wraparound, where the product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. this occurs when an integer value is incremented to a value that is too large to store in the associated representation. when this occurs, the value may become a very small or negative number. In Github.com/bettercap/bettercap/v2, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

A vulnerability was detected in bettercap up to 2.41.5. Affected by this vulnerability is the function ippReadChunkedBody of the file modules/zerogod/zerogod_ipp_primitives.go of the component zerogod IPP Service. Performing a manipulation results in integer coercion error. The attack can be initiated remotely. The attack is considered to have high complexity. The exploitation appears to be difficult. The exploit is now public and may be used. The patch is named 3731d5576cffae9eefe3721cd46a40933304129f. To fix this issue, it is recommended to deploy a patch.
