Description
This security bulletin contains information about 3 vulnerabilities.
1) Deserialization of untrusted data (CVE-ID: CVE-2017-17485)
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 in the FasterXML jackson-databind library due to improper validation of user-input handled by the readValue method of the ObjectMapper object. A remote attacker can send malicious input to the vulnerable method of a web application that uses the Spring library in the application's classpath and execute arbitrary code with elevated privileges.
Successful exploitation of the vulnerability may result in system compromise.
2) Deserialization of untrusted data (CVE-ID: CVE-2018-5968)
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:U/U:Amber
The vulnerability allows a remote attacker to execute arbitrary code.
The weakness exists due to deserialization flaw. A remote attacker can supply specially crafted input, execute arbitrary code and bypass a blacklist on the target system.
Successful exploitation of the vulnerability may result in system compromise.
3) Deserialization of untrusted data (CVE-ID: CVE-2018-7489)
CWE-ID: CWE-502 - Deserialization of Untrusted Data
CVSSv4: 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
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.
