In this post, we shall dive deep into a recently identified security vulnerability concerning IBM InfoSphere Information Server 11.7. Tagged with the Common Vulnerabilities and Exposures (CVE) identifier CVE-2022-22442, this weakness potentially permits an authenticated user to access information that should be confined to users with elevated privileges. IBM X-Force researchers uncovered this issue, and it has been allocated an X-Force ID of 224427.
To provide a comprehensive picture of this vulnerability, we will go through its details, presenting a code snippet and relevant links to original references while explaining how the exploit works. By the end of this long read, you should have a thorough understanding of CVE-2022-22442 and potential mitigation steps that can be taken.
IBM InfoSphere Information Server is a comprehensive suite of data integration, data quality, and data governance solutions. It is widely employed by organizations to manage and derive value from their data assets. As such, protecting these data assets is of utmost importance.
The CVE-2022-22442 vulnerability is a result of improper access controls within the IBM InfoSphere Information Server 11.7. Essentially, an authenticated user with lower privileges can exploit this weakness to gain unauthorized access to information or functionalities meant for users with higher privileges.
An attacker could leverage this security flaw to compromise sensitive organizational data, obtain unauthorized administrative privileges, and disrupt the availability or functionality of the application.
Here's a simplified code snippet that demonstrates the access control issue
class IBMInfoSphereServer: def __init__(self, user): self.user = user def has_elevated_privileges(self, user): if user.is_admin or user.is_manager: return True return False def restricted_function(self, user): if self.has_elevated_privileges(user): # Access to restricted information or functions return "Restricted information accessed." return "Access denied. Insufficient privileges." # Instantiate the InfoSphere Server info_server = IBMInfoSphereServer(user) # Access the restricted functionality result = info_server.restricted_function(user) # Output: "Restricted information accessed."
In this example, the restricted_function should only be accessible to users with elevated privileges (i.e., administrators or managers). However, due to the improper implementation of the has_elevated_privileges function in the IBM InfoSphere Information Server 11.7, an authenticated user with lower privileges can gain access to the restricted information or functionalities.

Exploiting this vulnerability requires an attacker to have access to a valid user account; they then need to devise a method to bypass the improper access controls. Once successful, the attacker would gain unauthorized access to sensitive data and restricted functionalities within the IBM InfoSphere Information Server 11.7.
IBM has released a patch to address this vulnerability, and it is recommended that organizations apply this patch as soon as possible. Additionally, organizations should monitor their environment for any suspicious user activities and review their user access management practices to minimize the risk of unauthorized access or compromise.
Understanding and addressing security issues such as CVE-2022-22442 is essential in ensuring the protection of vital data assets housed within the IBM InfoSphere Information Server. By being well-informed of the vulnerability and adopting the recommended mitigation steps, organizations can raise their resilience against potential threats and reduce the risks associated with unauthorized access to sensitive information.
