A newly identified vulnerability, CVE-2022-37015, has been discovered in Symantec Endpoint Detection and Response (SEDR) Appliance versions prior to 4.7.. The vulnerability could potentially allow an attacker to exploit the system and gain elevated access to resources within the application that are typically protected. In this long read post, we will go into the details of this vulnerability, investigate a code snippet related to it, and discuss the exploit details along with the original references for further reading.
Description of the Vulnerability
CVE-2022-37015 affects Symantec Endpoint Detection and Response (SEDR) Appliance versions before 4.7.. By exploiting this vulnerability, an attacker may be able to escalate their privilege level within the application, allowing them to access or manipulate resources that are usually protected against unauthorized users.
This specific vulnerability is a type of privilege escalation vulnerability, which is an issue where an attacker can compromise the software application to gain elevated access to protected resources. This is typically achieved by taking advantage of a weakness in the application's security model, allowing the attacker to bypass the usual restrictions.
Code Snippet
While the specific details of the code related to CVE-2022-37015 have not been released to the public, a typical privilege escalation vulnerability could be identified within code snippets that involve user authentication or permission validation. For example, in a hypothetical situation, the following code snippet may be vulnerable:
def authenticate_user(username, password):
user = get_user(username, password)
if user:
elevate_privileges(user)
else:
deny_access()
In the code snippet above, if an attacker were able to exploit vulnerabilities within the authenticate_user function, they might be able to bypass the deny_access() function and force the application to call elevate_privileges(user), granting them elevated access to the application's resources.
Exploit Details
To exploit this vulnerability, an attacker would first require access to the system running the vulnerable Symantec SEDR appliance. From there, they could identify and target the vulnerable code section or component to escalate their privileges.
Once the attacker has gained elevated privileges, they could potentially access sensitive configuration files, tamper with security settings, or even manipulate data. This could result in the application's functionality being compromised, allowing the attacker to perform actions such as data exfiltration, unauthorized access to resources, or even causing a denial of service.

Conclusion
In summary, CVE-2022-37015 is a privilege escalation vulnerability affecting Symantec Endpoint Detection and Response (SEDR) Appliance versions prior to 4.7.. By exploiting this vulnerability, an attacker could potentially gain elevated access to the system and its protected resources. It's crucial that affected systems be updated to the latest version of Symantec SEDR Appliance (4.7. or later) to mitigate the risk. Additionally, implementing proper monitoring and access control measures is essential to identify and prevent potential attacks leveraging this vulnerability.
