CVE-2022-37767
Arbitrary Code Execution vulnerability in pebble (Maven)
What is CVE-2022-37767 About?
This vulnerability in Pebble Templates 3.1.5 allows for a protection mechanism bypass, leading to arbitrary code execution when used with Springbok. An attacker can craft malicious templates to execute arbitrary code. Exploiting this could be straightforward for an attacker with template access.
Affected Software
Technical Details
The vulnerability in Pebble Templates 3.1.5 allows an attacker to bypass security mechanisms, specifically when integrated with the Springbok framework. This bypass enables arbitrary code execution. The exact mechanism likely involves leveraging template language features that, when combined with Springbok's context or reflection capabilities, allow for calling restricted methods or instantiating arbitrary objects. This might involve exploiting weaknesses in sandbox escaping, insecure serialization, or improper handling of dynamic code evaluation within the template engine, ultimately giving an attacker the ability to execute their own code on the server.
What is the Impact of CVE-2022-37767?
Successful exploitation may allow attackers to execute arbitrary code on the server, leading to full system compromise, data exfiltration, or installation of malware.
What is the Exploitability of CVE-2022-37767?
Exploitation of this Arbitrary Code Execution vulnerability would typically involve crafting a malicious Pebble template that bypasses the security mechanisms. The complexity level is moderate to high, as it requires specific knowledge of Pebble's template syntax, its security features, and how they interact with the Springbok framework. Authentication to submit or modify templates is likely a prerequisite. The attack could be remote if the application accepts user-supplied templates via a web interface or API. The primary risk factor is the deployment of vulnerable Pebble Template versions in environments where untrusted users can influence or control template content, especially when paired with Springbok.
