CVE-2020-3135    

CWE-352

CVSS Score:
6.5  AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:H/A:N/E:X/RL:X/RC:X

Summary

  o [CVE-2020-3135_su]

    A vulnerability in the web-based management interface of Cisco Unified
    Communications Manager (UCM) could allow an unauthenticated, remote
    attacker to conduct a cross-site request forgery (CSRF) attack on an
    affected device.

    The vulnerability is due to insufficient CSRF protections for the web-based
    management interface on an affected device. An attacker could exploit this
    vulnerability by persuading a user of the interface to follow a malicious
    link. A successful exploit could allow the attacker to perform arbitrary
    actions with the privilege level of the targeted user.

    Cisco has released software updates that address the vulnerability
    described in this advisory. There are no workarounds that address this
    vulnerability.

Summary

  o A vulnerability in the web-based management interface of Cisco Unified
    Communications Manager could allow an authenticated, remote attacker to
