Apache Tapestry HMAC secret key leak

This exploit finds the HMAC secret key used in Java serialization by Apache Tapestry. This key is located in the file AppModule.class by default and looks like the standard representation of UUID in hex digits hd : 6hd-4hd-4hd-4hd-12hd If the HMAC key has been changed to look differently, this...

GO-2020-0023 Timing side-channel in github.com/robbert229/jwt

Token validation methods are susceptible to a timing side-channel during HMAC comparison. With a large enough number of requests over a low latency connection, an attacker may use this to determine the expected HMAC...

GO-2020-0009 Integer overflow in github.com/square/go-jose

On 32-bit platforms an attacker can manipulate a ciphertext encrypted with AES-CBC with HMAC such that they can control how large the input buffer is when computing the HMAC authentication tag. This can can allow a manipulated ciphertext to be verified as authentic, opening the door for padding...

SUSE-SU-2021:0689-1 Security update for bind

This update for bind fixes the following issues: - dnssec-keygen can no longer generate HMAC keys. Use tsig-keygen instead. bsc1180933...

JSON Web Token Weak Secret

JSON Web Tokens can be signed to protect against data tampering. By using an asymmetric or a symmetric signing algorithm, the application computes a signature of the token data which will be verified during token decoding to ensure its integrity. When using a symmetric algorithm, the signature is...

Improper Key Verification

xml-crypto is vulnerable to improper key verification. An attacker can inject an HMAC-SHA1 signature that is valid using only knowledge of the RSA public key. This allows bypassing signature validation...

Improper Key Verification

Overview An attacker can inject an HMAC-SHA1 signature that is valid using only knowledge of the RSA public key. This allows bypassing signature validation. Recommendation Version 2.0.0 has the fix. The recommendation is to upgrade. In case that is not possible remove the...

Hash Collision

Bouncy Castle is vulnerable to hash collision attacks. The library keystore files uses a HMAC hash that is only 16 bits long, allowing a malicious user to retrieve the password used for keystore integrity verification checks. This vulnerability only affects users of the BKS-V1 keystore format,...

Validation Bypass

xml-crypto is vulnerable to validation bypass. The vulnerability exists through a possible key confusion by injecting a valid HMAC-SHA1 signature, as both HMAC and the public key digital signature methods key shares the same variable...

xml-crypto's HMAC-SHA1 signatures can bypass validation via key confusion

Impact An attacker can inject an HMAC-SHA1 signature that is valid using only knowledge of the RSA public key. This allows bypassing signature validation. Patches Version 2.0.0 has the fix. Workarounds The recommendation is to upgrade. In case that is not possible remove the...
