CVE-2013-0783: Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird befor

Noroxi assessment

Priority: Monitor (action score 38/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 4.6% (FIRST EPSS); higher than 91.8% of all records.
  • Fixed version: iceweasel (Debian:7) 17.0.6esr-1~deb7u1; devhelp (Red Hat:enterprise_linux:5::server) 0:0.12-23.el5_9; devhelp-debuginfo (Red Hat:enterprise_linux:5::server) 0:0.12-23.el5_9.

Low priority for now. Upgrade to iceweasel (Debian:7) 17.0.6esr-1~deb7u1; devhelp (Red Hat:enterprise_linux:5::server) 0:0.12-23.el5_9; devhelp-debuginfo (Red Hat:enterprise_linux:5::server) 0:0.12-23.el5_9 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

Multiple unspecified vulnerabilities in the browser engine in Mozilla Firefox before 19.0, Firefox ESR 17.x before 17.0.3, Thunderbird before 17.0.3, Thunderbird ESR 17.x before 17.0.3, and SeaMonkey before 2.16 allow remote attackers to cause a denial of service (memory corruption and application crash) or possibly execute arbitrary code via unknown vectors.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Timeline

From publication to today: proof of concept, Metasploit module, CISA KEV and fix record. Dates are as reported by the sources.

No dated events beyond publication.

No history yet (it accumulates with the daily EPSS job).

Patch and commit links

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

No commit or PR link among the references.

Credits

All researchers

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.
