Reference Description
CVE-2001-1141 PRNG allows attackers to use the output of small PRNG requests to determine
the internal state information, which could be used by attackers to predict
future pseudo-random numbers.

Notes
Maintenance
As of CWE 4.5, terminology related to randomness, entropy, and predictability can vary widely.
Within the developer and other communities, "randomness" is used heavily. However, within
cryptography, "entropy" is distinct, typically implied as a measurement. There are no commonlyused
definitions, even within standards documents and cryptography papers. Future versions of
CWE will attempt to define these terms and, if necessary, distinguish between them in ways that
are appropriate for different communities but do not reduce the usability of CWE for mapping,
understanding, or other scenarios.

CWE-341: Predictable from Observable State
Weakness ID : 341
Structure : Simple
Abstraction : Base
Description
A number or object is predictable based on observations that the attacker can make about the state
of the system or network, such as time, process ID, etc.
Relationships
The table(s) below shows the weaknesses and high level categories that are related to this
weakness. These relationships are defined as ChildOf, ParentOf, MemberOr and give insight to
similar items that may exist at higher and lower levels of abstraction. In addition, relationships such
as PeerOf and CanAlsoBe are defined to show similar weaknesses that may want to be explored.
