CVE-2011-5257 : 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.

# Exploit Title: WordPress Classipress Theme <= 3.1.4 Stored XSS # Date: 2011-09-26 # Author: Paul Loftness # Contact:http://attackvectorlabs.blogspot.com # Vendor: Appthemes LLc. # Product Web Page: http://www.appthemes.com/themes/classipress/ # Version: <=3.1.4 # Tested Versions: 3.1.4, 3.0.5.3 Summary: ------------------------- ClassiPress is a popular and widely used classified ads software for WordPress. Description: ------------------------- Classipress is vulnerable to multiple stored XSS vulnerabilities. Input through the POST parameters 'facebook_id' and 'twitter_id' in a registered user's profile page is either not sanitisized or poorly sanitised (version specific) allowing the attacker to insert Javascript code. In version 3.0.5.2 and presumably all previous versions, no sanitation is in place, allowing an attacker to insert code within a tag or to break out of it. In version 3.1.4, the less-than character is sanitised but an attacker can still insert quotes and place an event handler in the tag. Proof-of-Concept Code: ------------------------- Insertion page: http://example_site/author/profile/ Infected page : http://example_site/author/attacker_username/ Note: Some sites replace "author" with another path, this is not a vanilla configuration, however.
