Use of Cache Containing Sensitive Information

  • Vulnerable module: org.springframework.security:spring-security-web
  • Introduced through: org.ligoj.bootstrap:bootstrap-business@3.2.4

Detailed paths

  • Introduced through: ligoj/plugin-scm-git@ligoj/plugin-scm-git#6d1f4e7c695ea57bbfaa2a22884eb4ed96415240 › org.ligoj.bootstrap:bootstrap-business@3.2.4 › org.ligoj.bootstrap:bootstrap-core@3.2.4 › org.springframework.security:spring-security-web@6.5.7

Overview

org.springframework.security:spring-security-web is a package within Spring Security that provides security services for the Spring IO Platform.

Affected versions of this package are vulnerable to Use of Cache Containing Sensitive Information in the process of writing HTTP response headers for servlet applications. An attacker can manipulate HTTP responses by exploiting the failure to write expected headers, potentially leading to unauthorized access or information disclosure.

Remediation

Upgrade org.springframework.security:spring-security-web to version 6.5.9, 7.0.4 or higher.

Overview

com.fasterxml.jackson.core:jackson-core is a Core Jackson abstractions, basic JSON streaming API implementation

Affected versions of this package are vulnerable to Allocation of Resources Without Limits or Throttling in which the non-blocking async JSON parser can be made to bypass the maxNumberLength constraint (default: 1000 characters) defined in StreamReadConstraints. An attacker can cause excessive memory allocation and CPU exhaustion by submitting JSON documents containing extremely long numeric values through the asynchronous parser interface.

PoC

The following JUnit 5 test demonstrates the vulnerability. It shows that the async parser accepts a 5,000-digit number, whereas the limit should be 1,000.

 * Authors: sprabhav7, rohan-repos

Details

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

  • High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.

  • Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package

Remediation

Upgrade com.fasterxml.jackson.core:jackson-core to version 2.18.6, 2.21.1 or higher.

Overview

org.springframework:spring-web is a package that provides a comprehensive programming and configuration model for modern Java-based enterprise applications - on any kind of deployment platform.

Affected versions of this package are vulnerable to Improper Neutralization of Special Elements in Output Used by a Downstream Component ('Injection'). The vulnerability exists in the handling of Server-Sent Events (SSE) when streaming plain text data. An attacker can inject crafted data into the event stream, breaking message boundaries and corrupting the stream delivered to other clients. By controlling streamed content, an attacker can manipulate how subsequent events are parsed by the client, potentially altering application state or injecting misleading data.

Note:

This is only exploitable if the application streams attacker-controlled data via SSE using unstructured/plain-text messages instead of a structured format (e.g., JSON).

Remediation

Upgrade org.springframework:spring-web to version 6.2.17, 7.0.6 or higher.
