Combodo iTop is an open source, web-based IT service management platform. Prior to versions 2.7.8 and 3.0.2-1, the reset password token is generated without any randomness parameter. This may lead to account takeover. The issue is fixed in versions 2.7.8 and 3.0.2-1.

Weakness

The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.

Affected Software

Name Vendor Start Version End Version
Itop Combodo 2.0.2 (excluding) 2.7.8 (excluding)
Itop Combodo 3.0.0 (excluding) 3.0.2-1 (excluding)

Potential Mitigations

  • Use a well-vetted algorithm that is currently considered to be strong by experts in the field, and select well-tested implementations with adequate length seeds.
  • In general, if a pseudo-random number generator is not advertised as being cryptographically secure, then it is probably a statistical PRNG and should not be used in security-sensitive contexts.
  • Pseudo-random number generators can produce predictable numbers if the generator is known and the seed can be guessed. A 256-bit seed is a good starting point for producing a “random enough” number.
