Noroxi assessment

Priority: This week (action score 64/100)

A ready-made attack module is public (Metasploit, Nuclei); exploiting it takes no special expertise.
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: 80.9% (FIRST EPSS); higher than 99.6% 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.
Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

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.

Primary sources: NVD · CVE.org · FIRST EPSS

A vulnerability in the authentication system of Cisco Smart Software Manager On-Prem (SSM On-Prem) could allow an unauthenticated, remote attacker to change the password of any user, including administrative users. This vulnerability is due to improper implementation of the password-change process. An attacker could exploit this vulnerability by sending crafted HTTP requests to an affected device. A successful exploit could allow an attacker to access the web UI or API with the privileges of the compromised user.
