Observable Discrepancy

  • Vulnerable module: jsrsasign
  • Introduced through: jsrsasign@10.9.0

Detailed paths

  • Introduced through: @datebe/destroyclaim-js@datebe/destroyclaims#9a8a6e5e432312175cc439f333c45620924400fc › jsrsasign@10.9.0
    Remediation: Upgrade to jsrsasign@11.0.0.

Overview

jsrsasign is a free pure JavaScript cryptographic library.

Affected versions of this package are vulnerable to Observable Discrepancy via the RSA PKCS#1.5 or RSAOAEP decryption process. An attacker can decrypt ciphertexts by exploiting the Marvin security flaw. Exploiting this vulnerability requires the attacker to have access to a large number of ciphertexts encrypted with the same key.

Workaround

The vulnerability can be mitigated by finding and replacing RSA and RSAOAEP decryption with another crypto library.

Remediation

Upgrade jsrsasign to version 11.0.0 or higher.

Missing Release of Resource after Effective Lifetime

  • Vulnerable module: inflight
  • Introduced through: secure-rm@4.2.0

Detailed paths

  • Introduced through: @datebe/destroyclaim-js@datebe/destroyclaims#9a8a6e5e432312175cc439f333c45620924400fc › secure-rm@4.2.0 › rimraf@3.0.2 › 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.
