CVE-2013-5391

15
FAUCET Score

CVE-2013-5391 affects IBM Worklight and Mobile Foundation versions 5.0.x and 6.0.x, stemming from improper initialization of the pseudo-random number generator (PRNG) in Android when used by a Worklight program. This medium-severity vulnerability (CVSS 5.3) has a high impact on confidentiality, allowing attackers to more easily defeat cryptographic protections due to the weak randomness. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage.
