Uncontrolled resource consumption

  • Vulnerable module: braces
  • Introduced through: nodemon@3.1.0

Detailed paths

  • Introduced through: nogin@brettz9/nogin#8cf16cfa0a90dc026530cd12d25c6655219ac6ca nodemon@3.1.0 chokidar@3.6.0 braces@3.0.2

Overview

braces is a Bash-like brace expansion, implemented in JavaScript.

Affected versions of this package are vulnerable to Uncontrolled resource consumption due to failing to limit the number of characters it can handle, through the parse function. An attacker can cause the application to allocate excessive memory and potentially crash by sending imbalanced braces as input.

Remediation

There is no fixed version for braces.

Missing Release of Resource after Effective Lifetime

  • Vulnerable module: inflight
  • Introduced through: stylus@0.62.0

Detailed paths

  • Introduced through: nogin@brettz9/nogin#8cf16cfa0a90dc026530cd12d25c6655219ac6ca stylus@0.62.0 glob@7.2.3 inflight@1.0.6

Overview

Affected versions of this package are vulnerable to Missing Release of Resource after Effective Lifetime via the makeres function due to improperly deleting keys from the reqs object after execution of callbacks. This behavior causes the keys to remain in the reqs object, which leads to resource exhaustion.

Exploiting this vulnerability results in crashing the node process or in the application crash.

Note: This library is not maintained, and currently, there is no fix for this issue. To overcome this vulnerability, several dependent packages have eliminated the use of this library.

To trigger the memory leak, an attacker would need to have the ability to execute or influence the asynchronous operations that use the inflight module within the application. This typically requires access to the internal workings of the server or application, which is not commonly exposed to remote users. Therefore, “Attack vector” is marked as “Local”.

PoC

const inflight = require('inflight');

function testInflight() {
  let i = 0;
  function scheduleNext() {
    let key = `key-${i++}`;
    const callback = () => {
    };
    for (let j = 0; j < 1000000; j++) {
      inflight(key, callback);
    }

    setImmediate(scheduleNext);
  }


  if (i % 100 === 0) {
    console.log(process.memoryUsage());
  }

  scheduleNext();
}

testInflight();

Remediation

There is no fixed version for inflight.
