Common Weakness Enumeration

CWE-208

Allowed

Observable 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.

356 vulnerabilities reference this CWE, most recent first.

Details

The side-channel protected T-Table implementation in wolfSSL up to version 5.6.5 protects against a side-channel attacker with cache-line resolution. In a controlled environment such as Intel SGX, an attacker can gain a per instruction sub-cache-line resolution allowing them to break the cache-line-level protection.

Summary
Non-constant time comparison of inbound TCP agent connection secret
Details

Jenkins 2.218 and earlier, LTS 2.204.1 and earlier does not use a constant-time comparison validating the connection secret when an inbound TCP agent connection is initiated. This could potentially allow attackers to use statistical methods to obtain the connection secret.

Jenkins 2.219, LTS 2.204.2 now uses a constant-time comparison function for verifying connection secrets.

Summary
Minerva timing attack on P-256 in python-ecdsa
Details

python-ecdsa has been found to be subject to a Minerva timing attack on the P-256 curve. 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. Both ECDSA signatures, key generation, and ECDH operations are affected. ECDSA signature verification is unaffected. The python-ecdsa project considers side channel attacks out of scope for the project and there is no planned fix.

Summary
Mojic: Observable Timing Discrepancy in HMAC Verification
Details

Summary

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.

VLAI
Details

Cockpit CMS before 2.14.1 contains an account enumeration vulnerability in the auth check endpoint due to timing discrepancies in password verification. Attackers can measure response times across multiple requests to determine which accounts exist by observing that existing accounts trigger bcrypt verification while non-existent accounts return immediately.

Summary
Login timing attack in ezsystems/ezpublish-kernel
Details

Ibexa 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.
