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) 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.

3) Infinite loop
EUVDB-ID: #VU10381
Risk: Low
CVSSv4.0: 2.1 [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:P/U:Clear]
CVE-ID: CVE-2018-1041
CWE-ID:
CWE-835 - Loop with Unreachable Exit Condition ('Infinite Loop')
Exploit availability: Yes
DescriptionThe vulnerability allows an adjacent attacker to cause DoS condition on the target system.
The weakness exists due to an error when handling malicious input. An adjacent attacker can send specially crafted data to trigger an empty buffer read error in RemoteMessageChannel, consume excessive CPU resources and cause the application to enter an infinite loop and then the service to crash.

CPE2.3 External linkshttps://access.redhat.com/errata/RHSA-2018:0271
Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
4) 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.
