Official description

BMC FootPrints ITSM versions 20.20.02 through 20.24.01.001 contain a deserialization of untrusted data vulnerability in the ASP.NET servlet's VIEWSTATE handling that allows authenticated attackers to execute arbitrary code. Attackers can supply crafted serialized objects to the VIEWSTATE parameter to achieve remote code execution and fully compromise the application. The following hotfixes remediate the vulnerability: 20.20.02, 20.20.03.002, 20.21.01.001, 20.21.02.002, 20.22.01, 20.22.01.001, 20.23.01, 20.23.01.002, and 20.24.01.

The underlying weakness: Deserialization of Untrusted Data

The product deserializes untrusted data without sufficiently ensuring that the resulting data will be valid.

How developers prevent this class of flaw

  • If available, use the signing/sealing features of the programming language to assure that deserialized data has not been tainted. For example, a hash-based message authentication code (HMAC) could be used to ensure that data has not been modified.
  • When deserializing data, populate a new object rather than just deserializing. The result is that the data flows through safe input validation and that the functions are safe.
  • Explicitly define a final object() to prevent deserialization.
