Security Bulletin
This security bulletin contains information about 5 vulnerabilities.
1) Remote code execution
EUVDB-ID: #VU8541
Risk: High
CVSSv4.0: 9.3 [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:A/U:Amber]
CVE-ID: CVE-2017-12615
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists in Apache Tomcat when running on Windows with HTTP PUTs enabled (e.g. via setting the readonly initialisation parameter of the Default to false) due to input validation flaw. A remote attacker can send a specially crafted HTTP PUT request to upload an arbitrary JSP file to the target system and request the file to execute arbitrary code with privileges of the current user.
Successful exploitation of the vulnerability may result in system compromise.
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?
Yes. This vulnerability is being exploited in the wild.
2) Information disclosure
EUVDB-ID: #VU8543
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:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-12616
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists in the systems and resources using the VirtualDirContext due to input validation flaw. A remote attacker can send a specially crafted request to bypass security constraints and view JSP source code for resources on the target system served by the VirtualDirContext.
Successful exploitation of the vulnerability results in information disclosure.

3) Improper input validation
EUVDB-ID: #VU8669
Risk: High
CVSSv4.0: 9.3 [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:A/U:Amber]
CVE-ID: CVE-2017-12617
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: Yes
DescriptionThe vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to insufficient validation of user-supplied input when running with HTTP PUTs enabled. A remote attacker can send a specially crafted request to upload a JSP file to the server and execute arbitrary code on the system.
Successful exploitation of the vulnerability may result in full system compromise.

4) Security bypass
EUVDB-ID: #VU6950
Risk: Low
CVSSv4.0: 2.7 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-5664
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to bypass security restrictions on the target system.
The weakness exists due to improper handling of certain HTTP request methods for static error pages in Default Servlet. A remote attacker can bypass HTTP method restrictions and cause the error page to be deleted or replaced.
Successful exploitation of the vulnerability results in information modification.

5) Improper input validation
EUVDB-ID: #VU8697
Risk: Low
CVSSv4.0: 1.2 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2017-7674
CWE-ID:
CWE-20 - Improper input validation
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to conduct client and server side cache poisoning.
The weakness exists due to the failure to add an HTTP Vary header indicating that the response varies depending on Origin by the CORS Filter. A remote attacker can trick the victim to follow a specially crafted link and conduct client and server side cache poisoning.
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
