CVE-2022-46875: The executable file warning was not presented when downloading .atloc and .ftploc files, which can run commands on a user's computer.

Noroxi assessment

Priority: Monitor (action score 26/100)

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: 0.67% (FIRST EPSS); higher than 52.1% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. No special conditions are required; it is repeatable.
Fixed version: MozillaFirefox (openSUSE:Leap 15.3) 102.6.0-150200.152.70.1; MozillaThunderbird (openSUSE:Leap 15.3) 102.6.0-150200.8.96.1; MozillaFirefox (openSUSE:Tumbleweed) 108.0.1-1.1.

Low priority for now. Upgrade to MozillaFirefox (openSUSE:Leap 15.3) 102.6.0-150200.152.70.1; MozillaThunderbird (openSUSE:Leap 15.3) 102.6.0-150200.8.96.1; MozillaFirefox (openSUSE:Tumbleweed) 108.0.1-1.1 or later.

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.

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.

CWE-287 · Improper Authentication

CVSS vector

CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N

nvd-primary

Root cause

Authentication is added route by route instead of being enforced in one place. When a route added later bypasses the shared middleware, the session check never runs for it.

The bug in code

A representative example of this vulnerability class. Not the vendor's source code; it shows the faulty pattern and its fix.

Vulnerable

1app.use("/admin", requireSession, adminRouter);

Fixed
