Description
This security bulletin contains information about 4 secuirty vulnerabilities.
1) Deserialization of untrusted data (CVE-ID: CVE-2017-17485)
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)
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) Remote code execution (CVE-ID: CVE-2017-15095)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists in the jackson-databind development library due to improper implementation of blacklists for input handled by the ObjectMapper object readValue method. A remote unauthenticated attacker can send a malicious input and execute arbitrary code with elevated privileges.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Deserialization of untrusted data (CVE-ID: CVE-2017-7525)
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.
