Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Improper Isolation or Compartmentalization that allows an attacker who can convince a user to follow a malicious link to escape sandbox protections, due to a logic error in the Mojo component. This vulnerability does not enable code execution on its own, but is presumed chainable with another vulnerability to achieve code execution and has been observed in the wild.

Note: This vulnerability is only exploitable on Windows.

Remediation

Upgrade electron to version 33.4.8, 34.4.1, 35.1.2 or higher.

Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Integer Overflow or Wraparound via an incorrect count being passed to InstructionAccurateScope in the V8 engine. An attacker can cause heap corruption by enticing a user to visit a specially crafted HTML page.

Remediation

Upgrade electron to version 37.2.4 or higher.

Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Type Confusion. An attacker can access memory locations outside of the intended bounds by crafting a malicious HTML page that triggers type confusion in the V8 engine.

Remediation

Upgrade electron to version 31.7.2 or higher.

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.

Overview

electron is a framework which lets you write cross-platform desktop applications using JavaScript, HTML and CSS.

Affected versions of this package are vulnerable to Arbitrary Code Injection via modification of the resources folder when the embeddedAsarIntegrityValidation and onlyLoadAppFromAsar fuses are enabled. An attacker can execute unauthorized code by altering files within the application directory, bypassing ASAR integrity checks.

Note: This is only exploitable if the application is launched from a filesystem to which the attacker has write access.

Remediation

Upgrade electron to version 35.7.5, 36.8.1, 37.3.1, 38.0.0-beta.6 or higher.
