iDRAC9, versions prior to 7.00.00.172 for 14th Generation and 7.10.50.00 for 15th and 16th Generations, contains a session hijacking vulnerability in IPMI. A remote attacker could potentially exploit this vulnerability, leading to arbitrary code execution on the vulnerable application.
Weakness
The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.
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.
