CVE-2022-25237 is a critical vulnerability affecting Bonitasoft's Bonita Web version 2021.2. This vulnerability allows an authentication and authorization bypass due to an overly broad exclude pattern used in the RestAPIAuthorizationFilter. By appending ';i18ntranslation' or '/../i18ntranslation/' to the end of a URL, users without appropriate privileges can gain unauthorized access to privileged API endpoints. This could potentially lead to remote code execution by abusing the privileged API actions.
The severity of this vulnerability is classified as critical, with a CVSS score of 9.8. Such a high score indicates a significant risk to organizations that utilize this product, as it can allow attackers to execute arbitrary code remotely. Therefore, organizations should prioritize patching immediately to mitigate this risk.
Currently, there are no known exploits or public proof-of-concept (PoC) code available for this vulnerability. However, the critical nature of the vulnerability means that it should not be ignored.
Given the criticality and potential impact of this issue, organizations using Bonitasoft Bonita Web 2021.2 should take immediate action to assess their exposure and implement any necessary patches or mitigations.
Vulnerability Details
The vulnerability allows users with no privileges to access privileged API endpoints, which is due to a flaw in the RestAPIAuthorizationFilter. This design oversight enables unauthorized access, leading to a risk of remote code execution. The vulnerability was published on June 2, 2022, and is classified under CWE as an authentication/authorization bypass.
The CVSS score for this vulnerability is 9.8, indicating a critical severity level. The vulnerability is exploitable over a network with low complexity and does not require any privileges or user interaction, making it particularly dangerous.
Technical Analysis
The root cause of this vulnerability lies in the misconfiguration of the authorization filter. The overly broad exclude pattern fails to adequately restrict access, allowing unauthorized users to append specific strings to URLs to bypass authentication checks.
The attack vector is network-based, with low attack complexity, meaning that an attacker can exploit the vulnerability without advanced skills. No privileges are required, and user interaction is not needed for exploitation.
The impacts of this vulnerability are severe: it poses high risks to confidentiality, integrity, and availability, allowing attackers to execute arbitrary code and potentially gain control over the affected systems.
Risk & Impact Analysis
Organizations utilizing Bonitasoft Bonita Web 2021.2 face considerable risk due to this vulnerability. The potential for unauthorized access to privileged API endpoints can lead to significant impacts, including data breaches and unauthorized actions on behalf of legitimate users.
The blast radius for this vulnerability is extensive, as it can affect any organization using the vulnerable version of Bonita Web. The urgency for remediation is critical, given the possibility of remote code execution.
