Most open-source software offer cost-effective and transparent options for building apps and other digital products. However, they often face vulnerabilities. While many modern software depend on them, these vulnerabilities create weak links.
Since open-source security vulnerabilities are mostly public knowledge, malicious actors can exploit them more easily. Read on to discover the most common issues and how to deal with them.
1. Source Code Vulnerabilities
Defects in the source code can come from errors in the code itself. These defects, such as a lack of input field validation or penetration testing, create major open-source software vulnerabilities.
You can manage source code vulnerabilities by using Software Composition Analysis (SCA) and Static Application Security Testing (SAST). You can also perform manual reviews since automated checks do not always show accurate results.
2. Outdated Dependencies
Older or unpatched versions of many open-source libraries contain known weaknesses. Hence, using them creates security risks since hackers and malicious players can exploit these loopholes if not handled on time. To address this vulnerability, update these dependencies to their latest versions. Use automated tools to monitor the systems continually and perform vulnerability scans.
3. Insufficient Monitoring and Logging
Identifying and responding to security incidents becomes difficult without proper logging and monitoring. However, manually tracking these incidents can also be difficult. Instead, use open source security tools to monitor and keep comprehensive logs and records of all events. Set up these tools to create alerts for any irregular occurrences.
4. SQL Injections
Open-source apps can be prone to SQL code injection attacks that use malicious SQL scripts to manipulate backend data. These attacks typically access information that should not be displayed, including sensitive company information and private user data. To prevent SQL injections, use automated tools to test for weak points. Be sure to restrict database access, filter inputs, and use parameterized queries.
5. Cross-Site Scripting
Open-source web applications can be vulnerable to cross-site scripting (XSS) if they do not properly sanitize user input. In this case, an attacker sends malicious code as browser-side scripts to other end users.
To mitigate cross-site scripting attacks, implement output encoding, perform user input validation, and use a web app firewall. Perform penetration testing frequently to ensure your security infrastructure still holds.
6. Insecure Defaults
Open-source software sometimes comes with default configurations that are not entirely secure. These may include open ports and weak default passwords. In this case, leaving default settings unchanged creates security risks.
While developers often overlook them, they are common entry points for hackers. To deal with this issue, always adjust the default configurations before launching. Secure default admin accounts and use security baselines like CAPTCHA security.
7. Insecure Authentication
Insecurely handling sessions and authentications can create vulnerabilities when using open-source software. These can include credential theft and session hijacking, which occurs when hackers assume other users’ accounts.
To address this problem, implement multi-factor authentication and use secure password storage practices. Create strong password policies by adding rule-based password generators.
Endnote
Open-source software sometimes face several security vulnerabilities, including source code defects, outdated dependencies, and SQL injections. Insecure defaults, cross-site scripts, broken authentication, and lack of monitoring also pose security issues. You can deal with these issues by updating the dependencies, ensuring proper authentication, and using reliable vulnerability scanning tools.
