Infinite loop

  • Vulnerable module: brace-expansion
  • Introduced through: @electric-eloquence/vinyl-fs@3.0.9

Detailed paths

  • Introduced through: gulp@electric-eloquence/gulp#v3-lts › @electric-eloquence/vinyl-fs@3.0.9 › glob@7.2.3 › minimatch@3.1.5 › brace-expansion@1.1.13

Overview

brace-expansion is a Brace expansion as known from sh/bash

Affected versions of this package are vulnerable to Infinite loop through the expand function when processing a brace pattern with a zero step value. An attacker can cause the process to hang and exhaust system memory by supplying specially crafted input, such as {1..2..0}. This can lead to significant resource consumption and denial of service.

Workaround

This vulnerability can be mitigated by sanitizing strings passed to expand to ensure a step value of 0 is not used.

Remediation

Upgrade brace-expansion to version 5.0.5 or higher.

Missing Release of Resource after Effective Lifetime

  • Vulnerable module: inflight
  • Introduced through: @electric-eloquence/vinyl-fs@3.0.9

Detailed paths

  • Introduced through: gulp@electric-eloquence/gulp#v3-lts › @electric-eloquence/vinyl-fs@3.0.9 › 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.
