Analysis
by VulDB Data Team • 03/05/2023
The vulnerability identified as CVE-2020-36660 resides within the paxswill EVE Ship Replacement Program version 0.12.11, representing a significant security weakness that has been classified as problematic. This issue manifests in the user information handler component, specifically within the file src/evesrp/views/api.py, where improper processing of certain data elements creates exploitable conditions. The vulnerability's classification as information disclosure indicates that malicious actors can potentially access sensitive user data through carefully crafted inputs or requests. The remote attack vector means that this vulnerability can be exploited without physical access to the system, making it particularly dangerous for web-facing applications. The security implications extend beyond simple data exposure, as user information could potentially be leveraged for further attacks or identity theft operations.
The technical flaw within the User Information Handler component stems from inadequate input validation and processing mechanisms within the api.py file. When processing user-related data, the application fails to properly sanitize or validate incoming parameters, allowing attackers to manipulate the data flow in ways that reveal confidential information. This type of vulnerability aligns with CWE-20, which describes "Improper Input Validation" as a fundamental weakness that can lead to various security issues including information disclosure. The vulnerability's nature suggests that the application may be exposing internal data structures, user credentials, or other sensitive information through its API endpoints without proper authorization checks or data filtering mechanisms. The specific processing logic in the affected file appears to lack sufficient security controls to prevent unauthorized access to user information.
The operational impact of this vulnerability extends beyond immediate data exposure, creating potential pathways for more sophisticated attacks within the broader threat landscape. Attackers exploiting this vulnerability could gain access to user account details, personal information, or system metadata that could be used for identity theft, social engineering attacks, or as a stepping stone for additional compromises. The remote exploit capability means that threat actors can target this vulnerability from anywhere on the internet, potentially affecting a wide range of users without requiring physical presence or network access. This vulnerability also demonstrates poor security practices in API development, particularly around user information handling and access control mechanisms, which could indicate similar weaknesses in other parts of the application. The impact is further amplified by the fact that this vulnerability affects the core user information handling functionality, making it a critical component of the application's security posture.
Organizational security teams should prioritize immediate remediation of this vulnerability through the recommended upgrade to version 0.12.12, which includes the patch identified by the commit hash 9e03f68e46e85ca9c9694a6971859b3ee66f0240. This upgrade addresses the root cause by implementing proper input validation and data processing controls within the affected api.py file. System administrators should also conduct comprehensive security assessments of the application's API endpoints to identify any potential secondary vulnerabilities that may have been overlooked. The patch implementation should be followed by thorough testing to ensure that the upgrade does not introduce regressions or compatibility issues with existing functionality. Additionally, organizations should implement monitoring and logging mechanisms around user information handling components to detect potential exploitation attempts. Security best practices recommend that such vulnerabilities be addressed through proper vulnerability management processes, including risk assessment, impact analysis, and coordinated patch deployment. The ATT&CK framework would categorize this vulnerability under T1071.004 for Application Layer Protocol: DNS and potentially T1566 for Phishing, as attackers might leverage the exposed information for social engineering attacks. The vulnerability serves as a reminder of the importance of secure coding practices and proper input validation in preventing information disclosure scenarios.
