CVE-2021-42949: The component controlla_login function in HotelDruid Hotel Management Software v3.0.3 generates a predictable session token, allowing attack

Noroxi assessment

Priority: Plan (action score 41/100)

A ready-made attack module is public (Nuclei); exploiting it takes no special expertise.
Public proof-of-concept code exists (GitHub); there is no record of exploitation in the wild.
Probability of exploitation in the next 30 days: 7.2% (FIRST EPSS); higher than 94.3% 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.
Fixed version: hoteldruid (Debian:12) 3.0.4-1.

Add it to your regular patch cycle. Upgrade to hoteldruid (Debian:12) 3.0.4-1 or later.

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.
