CWE-208
AllowedObservable Timing Discrepancy
Abstraction: Base · Status: Incomplete
Two separate operations in a product require different amounts of time to complete, in a way that is observable to an actor and reveals security-relevant information about the state of the product, such as whether a particular operation was successful or not.

Using the ecdsa.SigningKey.sign_digest() API function and timing signatures an attacker can leak the internal nonce which may allow for private key discovery.

GHSA-WQQ3-WFMP-V85G
Vulnerability from github – Published: 2026-04-16 21:10 – Updated: 2026-04-27 16:08Summary
The CipherEngine in Mojic v2.1.3 uses a standard equality operator (!==) to verify the HMAC-SHA256 integrity seal during the decryption phase. This creates an Observable Timing Discrepancy (CWE-208), allowing a potential attacker to bypass the file integrity check via a timing attack.
Details
In lib/CipherEngine.js, the footer check validates the HMAC signature using a standard string comparison:
if (footerHex !== calcDigest) { ... }
Standard string comparisons in JavaScript short-circuit; they return false the moment a character mismatch occurs. Because the time taken to evaluate the comparison is proportional to the number of matching leading bytes, an attacker can measure the exact microseconds it takes for the engine to throw the FILE_TAMPERED error. By repeatedly altering the signature byte-by-byte and analyzing these minute timing differences, a malicious actor can theoretically forge a valid HMAC signature without possessing the decryption password.
PoC
The vulnerable implementation is located in lib/CipherEngine.js, within the getDecryptStream() flush method (approximately line 265):
// Vulnerable Code
if (footerHex !== calcDigest) {
this.emit('error', new Error("FILE_TAMPERED"));
return;
}
Recommended Remediation:
Replace the standard equality operator with Node.js's built-in constant-time comparison utility, crypto.timingSafeEqual().
// Remediated Code
const footerBuffer = Buffer.from(footerHex, 'hex');
const calcBuffer = Buffer.from(calcDigest, 'hex');
if (footerBuffer.length !== calcBuffer.length || !crypto.timingSafeEqual(footerBuffer, calcBuffer)) {
this.emit('error', new Error("FILE_TAMPERED"));
return;
}
Impact
If successfully exploited, an attacker could tamper with the encrypted .mojic payload and forge a valid HMAC signature. This bypasses the integrity seal, tricking the decryption engine into processing maliciously injected emoji streams. Because the engine translates these emojis back into C keywords and raw data chunks, this could ultimately result in arbitrary Code Injection into the restored .c source code when an unsuspecting user decrypts the tampered file.

GHSA-XFQG-P48G-HH94
Vulnerability from github – Published: 2022-06-02 21:02 – Updated: 2022-06-02 21:02Ibexa DXP is using random execution time to hinder timing attacks against user accounts, a method of discovering whether a given account exists in a system without knowing its password, thus affecting privacy. This implementation was found to not be good enough in some situations. The fix replaces this with constant time functionality, configured in the new security.yml parameter 'ibexa.security.authentication.constant_auth_time'. It will log a warning if the constant time is exceeded. If this happens the setting should be increased.

No mitigation information available for this CWE.
CAPEC-462: Cross-Domain Search Timing
An attacker initiates cross domain HTTP / GET requests and times the server responses. The timing of these responses may leak important information on what is happening on the server. Browser's same origin policy prevents the attacker from directly reading the server responses (in the absence of any other weaknesses), but does not prevent the attacker from timing the responses to requests that the attacker issued cross domain.
CAPEC-541: Application Fingerprinting
An adversary engages in fingerprinting activities to determine the type or version of an application installed on a remote target.
CAPEC-580: System Footprinting
An adversary engages in active probing and exploration activities to determine security information about a remote target system. Often times adversaries will rely on remote applications that can be probed for system configurations.
