Description
This security bulletin contains information about 14 secuirty vulnerabilities.
1) Deserialization of Untrusted Data (CVE-ID: CVE-2021-39145)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
2) Improper input validation (CVE-ID: CVE-2021-39139)
The vulnerability allows a remote authenticated user to execute arbitrary code.
The vulnerability exists due to improper input validation within the Tools (XStream) component in Oracle Utilities Testing Accelerator. A remote authenticated user can exploit this vulnerability to execute arbitrary code.
3) Deserialization of Untrusted Data (CVE-ID: CVE-2021-39148)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Improper input validation (CVE-ID: CVE-2021-39154)
The vulnerability allows a remote authenticated user to execute arbitrary code.
The vulnerability exists due to improper input validation within the Centralized Thirdparty Jars (XStream) component in Oracle Business Activity Monitoring. A remote authenticated user can exploit this vulnerability to execute arbitrary code.
5) Deserialization of Untrusted Data (CVE-ID: CVE-2021-39141)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-39150)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. 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.
7) Deserialization of Untrusted Data (CVE-ID: CVE-2021-39149)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
8) Improper input validation (CVE-ID: CVE-2021-39140)
The vulnerability allows a remote authenticated user to a crash the entire system.
The vulnerability exists due to improper input validation within the Policy (XStream) component in Oracle Communications Cloud Native Core Policy. A remote authenticated user can exploit this vulnerability to a crash the entire system.
9) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2021-39152)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input. 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.
10) Deserialization of Untrusted Data (CVE-ID: CVE-2021-39151)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
11) Deserialization of Untrusted Data (CVE-ID: CVE-2021-39147)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to insecure input validation when processing serialized data. A remote attacker can pass specially crafted data to the application and execute arbitrary code on the target system.
