Security Bulletin
This security bulletin contains information about 4 vulnerabilities.
EUVDB-ID: #VU23677
Risk: Medium
CVSSv3.1: 5 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-16559
CWE-ID:
CWE-284 - Improper Access Control
Exploit availability: No
DescriptionThe vulnerability allows a remote user to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to the affected software does not perform permission checks in methods performing form validation. A remote user with Overall/Read access can perform connection tests, determine whether files with an attacker-specified path exist on the Jenkins master file system, and obtain limited information about the Jenkins and plugin configuration based on the responses.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
Vulnerable software versionsWebSphere Deployer: 1.1 - 1.6.1

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote authenticated user via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU23679

CVSSv3.1: 5 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-16561
CWE-ID:
CWE-295 - Improper Certificate Validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a man-in-the-middle (MiTM) attack.
The vulnerability exists due to the affected software unconditionally
disables SSL/TLS certificate validation for the entire Jenkins master
JVM. A remote user with Overall/Read access can supply a specially crafted SSL/TLS
certificate, conduct man-in-the-middle attacks and disable SSL/TLS certificate and hostname validation for the entire
Jenkins master JVM, or specify a new Java keystore from a file stored on
the Jenkins master filesystem.
Cybersecurity Help is currently unaware of any official solution to address this vulnerability.

EUVDB-ID: #VU23678
Risk: Low
CVSSv3.1: 5.6 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N/E:U/RL:U/RC:C]
CVE-ID: CVE-2019-16560
CWE-ID:
CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
Exploit availability: No
DescriptionThe 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, such as perform connection tests, determine whether files with an attacker-specified path exist on the Jenkins master file system, and obtain limited information about the Jenkins and plugin configuration based on the responses.
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.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.

No. We are not aware of malware exploiting this vulnerability.
EUVDB-ID: #VU24767
Risk: High
CVSSv3.1: 7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:L/A:L/E:U/RL:U/RC:C]
CVE-ID: CVE-2020-2108
CWE-ID:
CWE-611 - Improper Restriction of XML External Entity Reference ('XXE')
Exploit availability: No
DescriptionThe vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to insufficient validation of user-supplied XML input. A remote user with Job/Configure permissions can pass a specially crafted war file containing a "WEB-INF/ibm-web-ext.xml" which is parsed by the plugin and view contents of arbitrary files on the system or initiate requests to external systems.
Successful exploitation of the vulnerability may allow an attacker to view contents of arbitrary file on the server or perform network scanning of internal and external infrastructure.
MitigationCybersecurity Help is currently unaware of any official solution to address this vulnerability.
