Multiple vulnerabilities in Adobe ColdFusion

1) Deserialization of untrusted data

EUVDB-ID: #VU8238

Risk: High

CVSSv3.1: 8.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-11283

CWE-ID: CWE-502 - Deserialization of Untrusted Data

Exploit availability: No

Description

The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The weakness exists due to improper validation of user-supplied data. A remote attacker can send a specially crafted file, trigger deserialization of untrusted data and execute arbitrary code under the context of the current process.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install update from vendor's website.

3) Cross-site scripting

EUVDB-ID: #VU8240

Risk: Low

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-11285

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 attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data. 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

Install update from vendor's website.

4) XXE attack

EUVDB-ID: #VU8241

Risk: Low

CVSSv3.1: 4.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2017-11286

CWE-ID: CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')

Exploit availability: No

Description

The vulnerability allows a remote attacker to conduct XXE attack.

The weakness exists in the encryption library due to improper handling of XML External Entity (XXE) entries when parsing an XML file. A remote attacker can send manipulated XML data and gain access to arbitrary data on the target system.

Successful exploitation of the vulnerability results in information disclosure..

Mitigation

Install update from vendor's website.
