Arbitrary Code Injection

  • Vulnerable module: serialize-javascript
  • Introduced through: mocha@10.8.2

Detailed paths

  • Introduced through: @theidentityselector/thiss@TheIdentitySelector/thiss-js#55becbc0a70041402bfb87a9567b19be2d4a0311 › mocha@10.8.2 › serialize-javascript@6.0.2

Overview

serialize-javascript is a package to serialize JavaScript to a superset of JSON that includes regular expressions and functions.

Affected versions of this package are vulnerable to Arbitrary Code Injection. An object like {"foo": /1"/, "bar": "a\"@__R-<UID>-0__@"} would be serialized as {"foo": /1"/, "bar": "a\/1"/}, meaning an attacker could escape out of bar if they controlled both foo and bar and were able to guess the value of <UID>. UID is generated once on startup, is chosen using Math.random() and has a keyspace of roughly 4 billion, so within the realm of an online attack.

PoC

eval('('+ serialize({"foo": /1" + console.log(1)/i, "bar": '"@__R-<UID>-0__@'}) + ')');

Remediation

Upgrade serialize-javascript to version 7.0.3 or higher.

Use of a Cryptographic Primitive with a Risky Implementation

  • Vulnerable module: elliptic
  • Introduced through: crypto-browserify@3.12.1

Detailed paths

  • Introduced through: @theidentityselector/thiss@TheIdentitySelector/thiss-js#55becbc0a70041402bfb87a9567b19be2d4a0311 › crypto-browserify@3.12.1 › browserify-sign@4.2.5 › elliptic@6.6.1
  • Introduced through: @theidentityselector/thiss@TheIdentitySelector/thiss-js#55becbc0a70041402bfb87a9567b19be2d4a0311 › crypto-browserify@3.12.1 › create-ecdh@4.0.4 › elliptic@6.6.1

Overview

elliptic is a fast elliptic-curve cryptography implementation in plain javascript.

Affected versions of this package are vulnerable to Use of a Cryptographic Primitive with a Risky Implementation due to the incorrect computation of the byte-length of k value with leading zeros resulting in its truncation. An attacker can obtain the secret key by analyzing both a faulty signature generated by a vulnerable implementation and a correct signature for the same inputs.

Note:

There is a distinct but related issue CVE-2024-48948.

Remediation

There is no fixed version for elliptic.

Missing Release of Resource after Effective Lifetime

  • Vulnerable module: inflight
  • Introduced through: mocha@10.8.2

Detailed paths

  • Introduced through: @theidentityselector/thiss@TheIdentitySelector/thiss-js#55becbc0a70041402bfb87a9567b19be2d4a0311 › mocha@10.8.2 › glob@8.1.0 › 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.
