Hi all, We recently received a report from Teguh P. Alko about an issue affecting Jenkins. Input was not sanitized before adding it to the page. The fix is public here since the start of 2013: https://github.com/jenkinsci/jenkins/commit/f8d2a0ba6c2e261f48287bdd95bd7a2d7a8d2d0e This could be used for copy and paste attacks, with the end result being similar to that of cross-site scripting attacks. It has been assigned CVE-2013-6488. Please credit at least "Teguh P. Alko" in any advisories. I am Cc'ing Reed to see if he knows who the other independent reporter is (from that Jira "SECURITY-46" bug in the above commit; as I understand it those bugs are not made public but I could be wrong). war/src/main/webapp/scripts/hudson-behavior.js @@ -1635,7 +1635,7 @@ function createSearchBox(searchURL) { function updatePos() { function max(a,b) { if(a>b) return a; else return b; } - sizer.innerHTML = box.value; + sizer.innerHTML = box.value.escapeHTML(); var w = max(sizer.offsetWidth,minW.offsetWidth); box.style.width = comp.style.width =
