New! Vulnerability Priority Rating (VPR)
Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.
VPR Score: 7.4
Synopsis
The SNMP server running on this host is affected by an authentication bypass vulnerability.
Description
SNMPv3 HMAC verification relies on the client to specify the HMAC length. This makes it possible for remote attackers to bypass SNMP authentication via repeated attempts with a HMAC length value of 1, which causes only the first byte of the authentication hash to be checked.
This issue affects SNMP implementations from multiple vendors.
Solution
This vulnerability affects multiple products from multiple vendors. Check with your vendor for the appropriate solution.
