Title
Suricata af-packet: defrag option can lead to truncated packets affecting visibility
Summary
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. The AF_PACKET defrag option is enabled by default and allows AF_PACKET to re-assemble fragmented packets before reaching Suricata. However the default packet size in Suricata is based on the network interface MTU which leads to Suricata seeing truncated packets. Upgrade to Suricata 7.0.9, which uses better defaults and adds warnings for user configurations that may lead to issues.

Title
Possibility to generate a session for any user via the "ex:action" parameter after obtaining access to the JWT key
Summary
An insufficiently secured internal function allows session generation for arbitrary users. The decodeParam function checks the JWT but does not verify which signing algorithm was used. As a result, an attacker can use the "ex:action" parameter in the VerifyUserByThrustedService function to generate a session for any user.

Title
MinIO performs incomplete signature validation for unsigned-trailer uploads
Summary
MinIO is a High Performance Object Storage released under GNU Affero General Public License v3.0. The signature component of the authorization may be invalid, which would mean that as a client you can use any arbitrary secret to upload objects given the user already has prior WRITE permissions on the bucket. Prior knowledge of access-key, and bucket name this user might have access
to - and an access-key with a WRITE permissions is necessary. However with relevant information in place, uploading random objects to buckets is trivial and easy via curl. This issue is fixed in RELEASE.2025-04-03T14-56-28Z.

Title
Absence of Kernel Module Signature Verification on Linux System of Infotainment ECU
Summary
The system suffers from the absence of a kernel module signature verification. If an attacker can execute commands on behalf of root user (due to additional vulnerabilities), then he/she is also able to load custom kernel modules to the kernel space and execute code in the kernel context. Such a flaw can lead to taking control over the entire system.
First identified on Nissan Leaf ZE1 manufactured in 2020.

Title
GoSign Desktop < 2.4.1 Insecure Update Mechanism RCE
Summary
GoSign Desktop versions 2.4.0 and earlier use an unsigned update manifest for distributing application updates. The manifest contains package URLs and SHA-256 hashes but is not digitally signed, so its authenticity relies solely on the underlying TLS channel. In affected versions, TLS certificate validation can be disabled when a proxy is configured, allowing an attacker who can intercept network traffic to supply a malicious update manifest and corresponding package with a matching hash. This can cause the client to download and install a tampered update, resulting in arbitrary code execution with the privileges of the GoSign Desktop user on Windows and macOS, or with elevated privileges on some Linux deployments. A local attacker who can modify proxy settings may also abuse this behavior to escalate privileges by forcing installation of a crafted update.

Title
Shuffle Master Deck Mate 2 Insecure Update Chain
Summary
Deck Mate 2's firmware update mechanism accepts packages without cryptographic signature verification, encrypts them with a single hard-coded AES key shared across devices, and uses a truncated HMAC for integrity validation. Attackers with access to the update interface - typically via the unit's USB update port - can craft or modify firmware packages to execute arbitrary code as root, allowing persistent compromise of the device's integrity and deck randomization process. Physical or on-premises access remains the most likely attack path, though network-exposed or telemetry-enabled deployments could theoretically allow remote exploitation if misconfigured. The vendor confirmed that firmware updates have been issued to correct these update-chain weaknesses and that USB update access has been disabled on affected units.

CVE-2025-34503 (GCVE-0-2025-34503)
Vulnerability from cvelistv5 – Published: 2025-10-24 23:04 – Updated: 2025-10-27 15:57
VLAI
Title
Shuffle Master Deck Mate 1 Unauthenticated EEPROM Firmware Execution
Summary
Deck Mate 1 executes firmware directly from an external EEPROM without verifying authenticity or integrity. An attacker with physical access can replace or reflash the EEPROM to run arbitrary code that persists across reboots. Because this design predates modern secure-boot or signed-update mechanisms, affected systems should be physically protected or retired from service. The vendor has not indicated that firmware updates are available for this legacy model.

CAPEC-463: Padding Oracle Crypto Attack
An adversary is able to efficiently decrypt data without knowing the decryption key if a target system leaks data on whether or not a padding error happened while decrypting the ciphertext. A target system that leaks this type of information becomes the padding oracle and an adversary is able to make use of that oracle to efficiently decrypt data without knowing the decryption key by issuing on average 128*b calls to the padding oracle (where b is the number of bytes in the ciphertext block). In addition to performing decryption, an adversary is also able to produce valid ciphertexts (i.e., perform encryption) by using the padding oracle, all without knowing the encryption key.
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.
