EPSS
EPSS est un modèle de notation qui prédit la probabilité qu'une vulnérabilité soit exploitée.
Score EPSS
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.
Percentile EPSS
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.

Details
Vendor Site: Oracle (www.oracle.com)
Date: April, 19th 2012 – CVE 2012-0550
Affected Software: Oracle GlassFish Server 3.1.1 (build 12)
Researcher: Roberto Suggi Liverani
PDF version: http://www.security-assessment.com/files/documents/advisory/Oracle_GlassFish_Server_REST_CSRF.pdf
Description
Security-Assessment.com has discovered that the Oracle GlassFish Server REST interface is vulnerable to Cross
Site Request Forgery (CSRF) attacks. Although the javax.faces.ViewState is employed in the standard web administrative interface and it prevents such attacks, the REST interface remains vulnerable, as shown in the Proof-of-Concept (PoC) below.
Exploitation
Cross Site Request Forgery attacks can target different functionality within an application. In this case, as an example, it is possible to force an authenticated administrator user into uploading an arbitrary WAR archive, which can be used to gain remote code execution on the server running the Oracle GlassFish Server application.
The Proof-of-Concept (PoC) below has been successfully tested with Firefox 8.0.1 and Chrome 15.0.874.121 with Basic Authentication enabled.
Arbitrary WAR Archive File Upload – CSRF PoC
<h1>Oracle GlassFish Server 3.1.1 (build 12) - CSRF arbitrary file upload</h1>by Roberto Suggi Liverani - Security-Assessment.com
This is a Proof-of-Concept - the start() function can be invoked automatically.
The CSRF upload technique used in this case is a slight variation of the technique demonstrated here:
