CVE-2018-3771 Explained : Impact and Mitigation
Learn about CVE-2018-3771, an XSS vulnerability in statics-server versions up to 0.0.9 allowing attackers to inject iframes into filenames, potentially leading to code execution and data theft.
Statics-server versions up to 0.0.9 are susceptible to an XSS vulnerability that allows attackers to inject iframes into the filename, potentially leading to exploitation when rendering the directory index in the browser.
Understanding CVE-2018-3771
Statics-server <= 0.0.9 is affected by a Cross-site Scripting (XSS) vulnerability, allowing malicious actors to execute attacks by manipulating filenames.
What is CVE-2018-3771?
This CVE identifies a security flaw in statics-server versions up to 0.0.9 that enables Cross-site Scripting (XSS) attacks through iframe injection in filenames during directory index rendering.
The Impact of CVE-2018-3771
The vulnerability poses a risk of unauthorized code execution and potential data theft when exploited by attackers injecting malicious iframes into filenames.
Technical Details of CVE-2018-3771
Statics-server <= 0.0.9 is affected by an XSS vulnerability that can be leveraged through injected iframes in filenames during directory index display.
Vulnerability Description
The XSS vulnerability in statics-server <= 0.0.9 allows threat actors to execute attacks by inserting iframes into filenames during directory index rendering.
Affected Systems and Versions
- Product: statics-server
- Vendor: HackerOne
- Vulnerable Version: 0.0.9
Exploitation Mechanism
Attackers exploit the XSS vulnerability by injecting iframes into filenames while statics-server renders the directory index in the browser.
Mitigation and Prevention
Taking immediate steps and implementing long-term security practices are crucial to mitigate the risks associated with CVE-2018-3771.
Immediate Steps to Take
- Update statics-server to a patched version beyond 0.0.9 to eliminate the XSS vulnerability.
- Implement input validation to prevent malicious iframe injections.
Long-Term Security Practices
- Regularly monitor and audit file rendering processes for any suspicious activities.
- Educate developers on secure coding practices to prevent XSS vulnerabilities.
Patching and Updates
