Description
This security bulletin contains information about 6 secuirty vulnerabilities.
1) Server-Side Request Forgery (SSRF) (CVE-ID: CVE-2022-22993)
The disclosed vulnerability allows a remote attacker to perform SSRF attacks.
The vulnerability exists due to insufficient validation of user-supplied input within the cgi_api endpoint. A remote user on the local network 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.
2) Insufficient verification of data authenticity (CVE-ID: CVE-2022-22994)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to lack of proper authentication of data received via HTTP within the ConnectivityService service. A remote attacker on the local network 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.
3) Command Injection (CVE-ID: CVE-2022-22991)
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to improper input validation within the ConnectivityService service. A remote attacker on the local network can pass specially crafted data to the application and execute arbitrary commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
4) Stack-based buffer overflow (CVE-ID: CVE-2022-22989)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to a boundary error within the FTP service. A remote attacker on the local network can trigger stack-based buffer overflow and execute arbitrary code on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
5) Command Injection (CVE-ID: CVE-2022-22992)
The vulnerability allows a remote attacker to execute arbitrary commands on the target system.
The vulnerability exists due to improper input validation. A remote unauthenticated attacker can pass specially crafted data to the application and execute arbitrary commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.
6) Improper Authentication (CVE-ID: CVE-2022-22990)
The vulnerability allows a remote attacker to bypass authentication process.
The vulnerability exists due to incorrect string matching logic when accessing protected pages within the nasAdmin service. A remote attacker on the local network can bypass authentication process and gain unauthorized access to the application.
