Security Bulletin

This security bulletin contains information about 5 vulnerabilities.

1) Input validation error

EUVDB-ID: #VU17778

Risk: High

CVSSv4.0: 8.1 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-14719

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to execute arbitrary code.

The vulnerability exists due to fail to block blaze-ds-opt and blaze-ds-core classes from polymorphic deserialization. A remote attacker can send a specially crafted request that submits malicious input to execute arbitrary code.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install update from vendor's website.

Vulnerable software versions

Multi-Enterprise Integration Gateway: before 1.0.0.8

B2B Advanced Communications: before 1.0.0.8

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

2) Remote code execution

EUVDB-ID: #VU17053

Risk: High

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-14718

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

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

The weakness exists due to the failure to block the slf4j-ext class from polymorphic deserialization. A remote attacker can execute arbitrary code with elevated privileges.

Mitigation

Install update from vendor's website.

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

3) Deserialization of untrusted data

EUVDB-ID: #VU11268

Risk: High

CVSSv4.0: 7.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Amber]

CVE-ID: CVE-2018-7489

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

Exploit availability: No

Description

The vulnerability allows a remote unauthenticated attacker to bypass security restrictions and execute arbitrary code on the target system.

The weakness exists in the readValue method due to improper validation of user-input. A remote attacker can send malicious JSON input, bypass security restrictions and execute arbitrary code with elevated privileges.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

Install update from vendor's website.

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.

Is there known malware, which exploits this vulnerability?

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

4) Server-Side Request Forgery (SSRF)

EUVDB-ID: #VU17776

Risk: Low

CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:L/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-14721

CWE-ID: CWE-918 - Server-Side Request Forgery (SSRF)

Exploit availability: No

Description

The disclosed vulnerability allows a remote attacker to perform SSRF attacks.

The vulnerability exists due to fail to block the axis2-jaxws class from polymorphic deserialization. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.

Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.

Mitigation

Install update from vendor's website.

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

5) Code Injection

EUVDB-ID: #VU25469

Risk: Medium

CVSSv4.0: 2.9 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:P/U:Green]

CVE-ID: CVE-2020-8840

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

Exploit availability: Yes

Description

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

The vulnerability exists due to absence of xbean-reflect/JNDI gadget blocking. A remote attacker can pass specially crafted input to the application and execute arbitrary Java code on the system, as demonstrated by org.apache.xbean.propertyeditor.JndiConverter.

Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

Mitigation

Install update from vendor's website.
