A vulnerability classified as problematic has been found in Chengdu Flash Flood Disaster Monitoring and Warning System 2.0. This affects an unknown part of the file /Service/ImageStationDataService.asmx of the component File Name Handler. The manipulation leads to insufficiently random values. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-235071. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.

Weakness

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

Affected Software

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.
