Multiple vulnerabilities in Cisco Unified Communications Manager

1) Cross-site scripting

EUVDB-ID: #VU13204

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-0340

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

Exploit availability: No

Description

The disclosed vulnerability allows a remote authenticated attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists in the web framework of the Cisco Unified Communications Manager (Unified CM) software due to insufficient input validation of certain parameters passed to the web server. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Mitigation

Update to versions 12.5(0.98000.265), 12.5(0.98000.779), 11.5(1.15900.16), 11.5(1.15900.15), 12.5(0.97000.265), 12.5(0.98000.653), 11.5(1.15900.8).

2) Cross-frame scripting

EUVDB-ID: #VU13205

Risk: Low

CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-0355

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute a cross-frame scripting (XFS) attack.

The weakness exists in the web UI of Cisco Unified Communications Manager (Unified CM) due to  insufficient protections for HTML inline frames (iframes) by the web UI. A remote attacker can trick the victim into visiting a specially crafted website, conduct XFS-attack and conduct click-jacking or other client-side browser attacks on the affected system.

Mitigation

Update to versions 11.5(1.15900.8), 12.5(0.98000.666), 12.5(0.98000.667)
