CVE-2020-27873: This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of NETGEAR R7450 1.2.0.62_1
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: 0.62% (FIRST EPSS); higher than 50.3% of all records.
- Someone on the same network segment can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
- According to the record, no fixed version is available yet.
Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS
This vulnerability allows network-adjacent attackers to disclose sensitive information on affected installations of NETGEAR R7450 1.2.0.62_1.0.1 routers. Authentication is not required to exploit this vulnerability. The specific flaw exists within the SOAP API endpoint, which listens on TCP port 80 by default. The issue results from the lack of proper access control. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-11559.
