XikeStor SKS8310-8X Network Switch firmware versions 1.04.B07 and prior contain a predictable session identifier vulnerability in the /goform/SetLogin endpoint that allows remote attackers to hijack authenticated sessions. Attackers can predict session identifiers using insufficiently random cookie values and exploit exposed session parameters in URLs to gain unauthorized access to authenticated user sessions.
Weakness
The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers.
Affected Software

| Zikestor_sks8310-8x_firmware | Seekswan | * | 1.04.b07 (including) |
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.
