Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Cross-site scripting

EUVDB-ID: #VU40380

Risk: Low

CVSSv3.1: 5 [AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N/E:U/RL:U/RC:C]

CVE-ID: CVE-2016-2058

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

Exploit availability: No

Description

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

The vulnerability exists due to insufficient sanitization of user-supplied data when processing data passed via an acknowledgement message, which is not properly handled in the "status" page. 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

Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

Vulnerable software versions

Debian Linux: 8.0

Xymon: 4.1.0 - 8.0

2) Buffer overflow

EUVDB-ID: #VU40384

Risk: High

CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2016-2054

CWE-ID: CWE-119 - Memory corruption

Exploit availability: No

Description

The vulnerability allows a remote non-authenticated attacker to execute arbitrary code.

Multiple buffer overflows in xymond/xymond.c in xymond in Xymon 4.1.x, 4.2.x, and 4.3.x before 4.3.25 allow remote attackers to execute arbitrary code or cause a denial of service (daemon crash) via a long filename, involving handling a "config" command.
