CVE-2007-3844· NVD / CVE Program· CNA redhat

Mozilla Firefox 2.0.0.5, Thunderbird 2.0.0.5 and before 1.5.0.13, and SeaMonkey 1.1.3 allows remote attackers to conduct cross-site scriptin

Noroxi assessment

Priority: Monitor (action score 19/100)

  • Public proof-of-concept code exists (Exploit-DB); there is no record of exploitation in the wild.
  • Probability of exploitation in the next 30 days: 5.4% (FIRST EPSS); higher than 92.5% of all records.
  • Fixed version: iceape (Debian:4.0) 1.0.10~pre070720-0etch3; icedove (Debian:4.0) 1.5.0.13+1.5.0.14b.dfsg1-0etch1; iceweasel (Debian:4.0) 2.0.0.6-0etch1.

Low priority for now. Upgrade to iceape (Debian:4.0) 1.0.10~pre070720-0etch3; icedove (Debian:4.0) 1.5.0.13+1.5.0.14b.dfsg1-0etch1; iceweasel (Debian:4.0) 2.0.0.6-0etch1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Mozilla Firefox 2.0.0.5, Thunderbird 2.0.0.5 and before 1.5.0.13, and SeaMonkey 1.1.3 allows remote attackers to conduct cross-site scripting (XSS) attacks with chrome privileges via an addon that inserts a (1) javascript: or (2) data: link into an about:blank document loaded by chrome via (a) the window.open function or (b) a content.location assignment, aka "Cross Context Scripting." NOTE: this issue is caused by a CVE-2007-3089 regression.

Patch and commit links

Commit, PR and diff links among the references. A starting point for patch-diffing and variant hunting; fixes, not exploits.

Finders, reporters and analysts named in the CNA record. Click a name for that researcher’s other records.

No credits in the CNA record.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.

No nightly-computed relations.

Chain candidates

An authentication bypass and a privilege-requiring bug in the same product, published close together: combined they may become an unauthenticated path.
