1) Insecure DLL loading

EUVDB-ID: #VU11680

Risk: Low

CVSSv3.1: 7.7 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2018-4938

CWE-ID: CWE-427 - Uncontrolled Search Path Element

Exploit availability: No

Description

The vulnerability allows a local attacker to gain elevated privileges on vulnerable system.

The weakness exists due to insecure .dll loading mechanism when opening files. A local attacker can place a file along with specially crafted .dll file on a remote SBM or WebDAV share and execute arbitrary code on the target system with elevated privileges.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

No. This vulnerability can be exploited locally. The attacker should have authentication credentials and successfully authenticate on the system.

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Deserialization of untrusted data

EUVDB-ID: #VU11681

Risk: High

CVSSv3.1: 9.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H/E:H/RL:O/RC:C]

CVE-ID: CVE-2018-4939

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

Exploit availability: No

Description

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

The weakness exists due to insufficient validation of user-supplied input. A remote attacker can send a specially crafted input, trigger deserialization flaw and execute arbitrary code on the target system with elevated privileges.

Successful exploitation of the vulnerability may allow an attacker to compromise vulnerable system.

Mitigation

Install update from vendor's website.

3) Cross-site scripting

EUVDB-ID: #VU11682

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-2018-4940

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.
