SSRF vulnerabilities occur when an API fetches a remote resource using a user-supplied Uniform Resource Identifier (URI) without adequate validation. This oversight allows attackers to manipulate the request, coercing the server to interact with unintended destinations. These attacks bypass traditional network controls like firewalls and VPNs, making them particularly insidious.
APIs enable various business flows, such as purchasing tickets, booking reservations, or posting comments. However, these flows can become liabilities if they are exposed without sufficient protections. *Unrestricted Access to Sensitive Business Flows* refers to a scenario where APIs fail to:
1. Limit access to sensitive operations.
2. Implement controls to prevent abuse, particularly by automated systems (e.g., bots).
3. Consider the broader business implications of such unrestricted access.
For instance, an API for purchasing event tickets might allow unlimited purchases by the same user or bot, leading to scalping and significant financial losses for legitimate customers.
API3:2023 represents a nuanced security challenge where improper or absent authorisation checks allow attackers to access or manipulate sensitive properties of an object within an API. Unlike broader access control issues, this risk focuses specifically on granular authorisation, which determines the visibility or modifiability of individual object properties.
LDAP Injection attacks are a severe and growing threat, with the potential to compromise sensitive data, escalate privileges, and disrupt business operations. Real-world incidents have demonstrated the wide-ranging consequences of such vulnerabilities, including financial losses, reputational damage, and regulatory repercussions.
By understanding the risks associated with LDAP Injection and adopting best practices for mitigation, organisations can protect themselves from these types of attacks. Regular security assessments, input validation, and the use of secure coding practices are essential for preventing LDAP Injection vulnerabilities and safeguarding against the potentially devastating impacts of these attacks.
LDAP Injection is a critical vulnerability that can have devastating consequences for an organisation, ranging from unauthorised data access to privilege escalation. By understanding how LDAP Injection works, the risks it presents, and the steps that can be taken to identify and mitigate it, penetration testers can play a pivotal role in strengthening the security posture of an organisation.
SSRF occurs when an attacker exploits a server-side vulnerability to send crafted requests from a vulnerable web server to unintended locations. These requests can be directed to internal services, cloud metadata APIs, or other network resources that would otherwise be inaccessible to external users. Essentially, SSRF enables attackers to leverage the server’s trust in internal resources and APIs to bypass firewalls, access private services, and gather sensitive data.
