CVE-2023-50919: An issue was discovered on GL.iNet devices before version 4.5.0.

CriticalCVSS 9.8 · v3.1—Weaponized No fix recorded

Noroxi assessment

Priority: This week (action score 60/100)

A ready-made attack module is public (Metasploit); exploiting it takes no special expertise.
A ready-made attack tool exists and the flaw can be exploited over the network without an account, so priority is at least “This week”.
Probability of exploitation in the next 30 days: 47.8% (FIRST EPSS); higher than 98.8% of all records.
Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
According to CISA the attack is automatable: targets can be found by mass scanning.
According to the record, no fixed version is available yet.

Don’t wait for the next maintenance window. Until a fix is released, restrict access to the affected component and follow the vendor's advisory.

Weakness class (CWE)

CWE-287 · Improper Authentication

CVSS vector

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

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.

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

Vulnerable
