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: 3.6
SynopsisA telephony application running on the remote host is affected by an information disclosure vulnerability.
DescriptionAccording to its SIP banner, the version of Asterisk running on the remote host is 11.x prior to 11.25.3, 13.x prior to 13.17.2, 14.x prior to 14.6.2, 11.6 prior to 11.6-cert18, or 13.13 prior to 13.13-cert6. It is therefore, affected by an information disclosure vulnerability due to insufficient RTCP packet validation. A remote attacker could potentially read buffer contents and redirect where the next RTCP report goes.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
SolutionUpgrade to Asterisk version 11.25.3 / 13.17.2 / 14.6.2 / 11.6-cert18 / 13.13-cert6 or later.
