Denial of Service (DoS)

  • Vulnerable module: ch.qos.logback:logback-classic
  • Introduced through: ch.qos.logback:logback-classic@V.logback

Detailed paths

  • Introduced through: laserdisc-io/laserdisc@laserdisc-io/laserdisc#59e79dd5d1d78ae23573ce9f1f7b3884ba2f8ed8 › ch.qos.logback:logback-classic@V.logback
    Remediation: Upgrade to ch.qos.logback:logback-classic@1.2.13.

Overview

ch.qos.logback:logback-classic is a reliable, generic, fast and flexible logging library for Java.

Affected versions of this package are vulnerable to Denial of Service (DoS). An attacker can mount a denial-of-service attack by sending poisoned data. This is only exploitable if logback receiver component is deployed.

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 ch.qos.logback:logback-classic to version 1.2.13, 1.3.12, 1.4.12 or higher.

Uncontrolled Resource Consumption ('Resource Exhaustion')

  • Vulnerable module: ch.qos.logback:logback-classic
  • Introduced through: ch.qos.logback:logback-classic@V.logback

Detailed paths

  • Introduced through: laserdisc-io/laserdisc@laserdisc-io/laserdisc#59e79dd5d1d78ae23573ce9f1f7b3884ba2f8ed8 › ch.qos.logback:logback-classic@V.logback
    Remediation: Upgrade to ch.qos.logback:logback-classic@1.2.13.

Overview

ch.qos.logback:logback-classic is a reliable, generic, fast and flexible logging library for Java.

Affected versions of this package are vulnerable to Uncontrolled Resource Consumption ('Resource Exhaustion') via the logback receiver component. An attacker can mount a denial-of-service attack by sending poisoned data.

Note:

Successful exploitation requires the logback-receiver component being enabled and also reachable by the attacker.

Remediation

Upgrade ch.qos.logback:logback-classic to version 1.2.13, 1.3.14, 1.4.14 or higher.
