Noroxi assessment

Priority: Plan (action score 46/100)

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: 23.7% (FIRST EPSS); higher than 97.8% 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.
Fixed version: resiprocate (Debian:8) 1:1.9.7-5+deb8u1; resiprocate (Debian:9) 1:1.11.0~beta1-3+deb9u2.

Add it to your regular patch cycle. Upgrade to resiprocate (Debian:8) 1:1.9.7-5+deb8u1; resiprocate (Debian:9) 1:1.11.0~beta1-3+deb9u2 or later.

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.

Weakness class (CWE)

CWE-120 · Buffer Copy without Checking Size of Input ('Classic Buffer Overflow')

CVSS vector

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

Root cause

When data is copied, the source length is not compared with the size of the destination buffer. Excess data overwrites adjacent memory.

The bug in code
