Description
This security bulletin contains information about 5 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2018-14719)
The disclosed vulnerability allows a remote attacker to execute arbitrary code.
The vulnerability exists due to fail to block blaze-ds-opt and blaze-ds-core classes from polymorphic deserialization. A remote attacker can send a specially crafted request that submits malicious input to execute arbitrary code.
Successful exploitation of the vulnerability may result in system compromise.
2) Remote code execution (CVE-ID: CVE-2018-14718)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.The weakness exists due to the failure to block the slf4j-ext class from polymorphic deserialization. A remote attacker can execute arbitrary code with elevated privileges.
3) Deserialization of untrusted data (CVE-ID: CVE-2018-7489)
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.
4) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2018-14721)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to fail to block the axis2-jaxws class from polymorphic deserialization. A remote attacker can send a specially crafted HTTP request and trick the application to initiate requests to arbitrary systems.
Successful exploitation of this vulnerability may allow a remote attacker gain access to sensitive data, located in the local network or send malicious requests to other servers from the vulnerable system.
5) Code Injection (CVE-ID: CVE-2020-8840)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to absence of xbean-reflect/JNDI gadget blocking. A remote attacker can pass specially crafted input to the application and execute arbitrary Java code on the system, as demonstrated by org.apache.xbean.propertyeditor.JndiConverter.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
