CWE-208
Observable Timing Discrepancy
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.

Title
Apache Hive: Timing Attack Against Signature in LLAP util
Summary
Use of Arrays.equals() in LlapSignerImpl in Apache Hive to compare message signatures allows attacker to forge a valid signature for an arbitrary message byte by byte. The attacker should be an authorized user of the product to perform this attack. Users are recommended to upgrade to version 4.0.0, which fixes this issue.
The problem occurs when an application doesn’t use a constant-time algorithm for validating a signature. The method Arrays.equals() returns false right away when it sees that one of the input’s bytes are different. It means that the comparison time depends on the contents of the arrays. This little thing may allow an attacker to forge a valid signature for an arbitrary message byte by byte. So it might allow malicious users to submit splits/work with selected signatures to LLAP without running as a privileged user, potentially leading to DDoS attack.
More details in the reference section.

CVE-2024-2467 (GCVE-0-2024-2467)

Title
Perl-crypt-openssl-rsa: side-channel attack in pkcs#1 v1.5 padding mode (marvin attack)
Summary
A timing-based side-channel flaw exists in the perl-Crypt-OpenSSL-RSA package, which could be sufficient to recover plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.

Vulnerability from cvelistv5 – Published: 2024-03-14 18:47 – Updated: 2024-08-26 15:21

Title
Username timing attack on recover password/MFA token in vantage6
Summary
vantage6 is an open source framework built to enable, manage and deploy privacy enhancing technologies like Federated Learning and Multi-Party Computation. Much like GHSA-45gq-q4xh-cp53, it is possible to find which usernames exist in vantage6 by calling the API routes `/recover/lost` and `/2fa/lost`. These routes send emails to users if they have lost their password or MFA token. This issue has been addressed in commit `aecfd6d0e` and is expected to ship in subsequent releases. Users are advised to upgrade as soon as a new release is available. There are no known workarounds for this vulnerability.

Much like GHSA-45gq-q4xh-cp53, it is possible to find which usernames exist in vantage6 by calling the API routes `/recover/lost` and `/2fa/lost`. These routes send emails to users if they have lost their password or MFA token. This issue has been addressed in commit `aecfd6d0e` and is expected to ship in subsequent releases. Users are advised to upgrade as soon as a new release is available. There are no known workarounds for this vulnerability."

CVE-2024-3296 (GCVE-0-2024-3296)
Vulnerability from cvelistv5 – Published: 2024-04-04 13:47 – Updated: 2026-02-25 19:31

Title
Rust-openssl: timing based side-channel can lead to a bleichenbacher style attack
Summary
A timing-based side-channel flaw exists in the rust-openssl package, which could be sufficient to recover a plaintext across a network in a Bleichenbacher-style attack. To achieve successful decryption, an attacker would have to be able to send a large number of trial messages for decryption. The vulnerability affects the legacy PKCS#1v1.5 RSA encryption padding mode.

Title
Control-flow timing leak in Kyber reference implementation when compiled with Clang 15-18 for -Os, -O1 and other options
Summary
liboqs is a C-language cryptographic library that provides implementations of post-quantum cryptography algorithms. A control-flow timing lean has been identified in the reference implementation of the Kyber key encapsulation mechanism when it is compiled with Clang 15-18 for `-Os`, `-O1`, and other compilation options. A proof-of-concept local attack on the reference implementation leaks the entire ML-KEM 512 secret key in ~10 minutes using end-to-end decapsulation timing measurements. The issue has been fixed in version 0.10.1. As a possible workaround, some compiler options may produce vectorized code that does not leak secret information, however relying on these compiler options as a workaround may not be reliable.

CVE-2024-40640 (GCVE-0-2024-40640)

Title
Usage of non-constant time base64 decoder could lead to leakage of secret key material in vodozemac
Summary
vodozemac is an open source implementation of Olm and Megolm in pure Rust. Versions before 0.7.0 of vodozemac use a non-constant time base64 implementation for importing key material for Megolm group sessions and `PkDecryption` Ed25519 secret keys. This flaw might allow an attacker to infer some information about the secret key material through a side-channel attack. The use of a non-constant time base64 implementation might allow an attacker to observe timing variations in the encoding and decoding operations of the secret key material. This could potentially provide insights into the underlying secret key material. The impact of this vulnerability is considered low because exploiting the attacker is required to have access to high precision timing measurements, as well as repeated access to the base64 encoding or decoding processes. Additionally, the estimated leakage amount is bounded and low according to the referenced paper. This has been patched in commit 734b6c6948d4b2bdee3dd8b4efa591d93a61d272 which has been included in release version 0.7.0. Users are advised to upgrade. There are no known workarounds for this vulnerability.

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.
