Description
This security bulletin contains information about 3 vulnerabilities.
1) Deserialization of untrusted data (CVE-ID: CVE-2017-5645)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists receiving serialized log events from another application when using the TCP socket server or UDP socket server. A remote attacker can submit a specially crafted binary payload, when deserialized, and execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
2) Security bypass (CVE-ID: CVE-2017-5664)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: 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
The 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.
3) Deserialization of untrusted data (CVE-ID: CVE-2017-7525)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 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:P/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to a deserialization flaw in the jackson-databind component. A remote attacker can send a specially crafted input to the readValue method of the ObjectMapper and execute arbitrary code with privileges of the target service.
Successful exploitation of the vulnerability may result in system compromise.
