CVSS v3.1 |
| On Mercku M6a devices through 2.1.0, the authentication system uses predictable session tokens based on timestamps. |
| When connecting to the Solax Cloud MQTT server the username is the "registration number", which is the 10 character string printed on the SolaX Power Pocket device / the QR code on the device. The password is derived from the "registration number" using a proprietary XOR/transposition algorithm. Attackers with the knowledge of the registration numbers can connect to the MQTT server and impersonate the dongle / inverters. |
| Guzzle OAuth Subscriber signs Guzzle requests using OAuth 1.0. Prior to 0.8.1, Nonce generation does not use sufficient entropy nor a cryptographically secure pseudorandom source. This can leave servers vulnerable to replay attacks when TLS is not used. This vulnerability is fixed in 0.8.1. |
| In RNP version 0.18.0 a refactoring regression causes the symmetric
session key used for Public-Key Encrypted Session Key (PKESK) packets to
be left uninitialized except for zeroing, resulting in it always being
an all-zero byte array.
Any data encrypted using public-key encryption
in this release can be decrypted trivially by supplying an all-zero
session key, fully compromising confidentiality.
The vulnerability affects only public key encryption (PKESK packets). Passphrase-based encryption (SKESK packets) is not affected.
Root cause: Vulnerable session key buffer used in PKESK packet generation.
The defect was introduced in commit `7bd9a8dc356aae756b40755be76d36205b6b161a` where initialization
logic inside `encrypted_build_skesk()` only randomized the key for the
SKESK path and omitted it for the PKESK path. |
| Vision UI is a collection of enterprise-grade, dependency-free modules for modern web projects. In versions 1.4.0 and below, the getSecureRandomInt function in security-kit versions prior to 3.5.0 (packaged in Vision-ui <= 1.4.0) contains a critical cryptographic weakness. Due to a silent 32-bit integer overflow in its internal masking logic, the function fails to produce a uniform distribution of random numbers when the requested range between min and max is larger than 2³². The root cause is the use of a 32-bit bitwise left-shift operation (<<) to generate a bitmask for the rejection sampling algorithm. This causes the mask to be incorrect for any range requiring 32 or more bits of entropy. This issue is fixed in version 1.5.0. |
| Generation of weak and predictable Initialization Vector (IV) in PMFW (Power Management Firmware) may allow an attacker with privileges to reuse IV values to reverse-engineer debug data, potentially resulting in information disclosure. |
| Thinbus Javascript Secure Remote Password is a browser SRP6a implementation for zero-knowledge password authentication. In versions 2.0.0 and below, a protocol compliance bug causes the client to generate a fixed 252 bits of entropy instead of the intended bit length of the safe prime (defaulted to 2048 bits). The client public value is being generated from a private value that is 4 bits below the specification. This reduces the protocol's designed security margin it is now practically exploitable. The servers full sized 2048 bit random number is used to create the shared session key and password proof. This is fixed in version 2.0.1. |
| Catalyst::Plugin::Session before version 0.44 for Perl generates session ids insecurely.
The session id is generated from a (usually SHA-1) hash of a simple counter, the epoch time, the built-in rand function, the PID and the current Catalyst context. This information is of low entropy. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
Predicable session ids could allow an attacker to gain access to systems. |
| A vulnerability was identified in the password generation algorithm when accessing the debug-interface. An unauthenticated local attacker with knowledge of the password generation timeframe might be able to brute force the password in a timely manner and thus gain root access to the device if the debug interface is still enabled. |
| A Use of Weak Credentials vulnerability affecting the Wi-Fi network generated by a set of DJI drones could allow a remote attacker to derive the WPA2 PSK key and authenticate without permission to the drone’s Wi- Fi network. This, in turn, allows the attacker to perform unauthorized interaction with the network services exposed by the drone and to potentially decrypt the Wi-Fi traffic exchanged between the drone and the Android/IOS device of the legitimate user during QuickTransfer mode. Affected models are Mavic 3 Pro until v01.01.0300, Mavic 3 until v01.00.1200, Mavic 3 Classic until v01.00.0500, Mavic 3 Enterprise until v07.01.10.03, Matrice 300 until v57.00.01.00, Matrice M30 until v07.01.0022 and Mini 3 Pro until v01.00.0620. |
| The Net::EasyTCP package before 0.15 for Perl always uses Perl's builtin rand(), which is not a strong random number generator, for cryptographic keys. |
| An issue was discovered in AdaCore ada_web_services 20.0 allows an attacker to escalate privileges and steal sessions via the Random_String() function in the src/core/aws-utils.adb module. |
| Starch versions 0.14 and earlier generate session ids insecurely.
The default session id generator returns a SHA-1 hash seeded with a counter, the epoch time, the built-in rand function, the PID, and internal Perl reference addresses. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not leaked from the HTTP Date header. The built-in rand function is unsuitable for cryptographic usage.
Predicable session ids could allow an attacker to gain access to systems. |
| Crypt::Salt for Perl version 0.01 uses insecure rand() function when generating salts for cryptographic purposes. |
| tgt (aka Linux target framework) before 1.0.93 attempts to achieve entropy by calling rand without srand. The PRNG seed is always 1, and thus the sequence of challenges is always identical. |
| The Crypt::Random::Source package before 0.13 for Perl has a fallback to the built-in rand() function, which is not a secure source of random bits. |
| Business::OnlinePayment::StoredTransaction versions through 0.01 for Perl uses an insecure secret key.
Business::OnlinePayment::StoredTransaction generates a secret key by using a MD5 hash of a single call to the built-in rand function, which is unsuitable for cryptographic use.
This key is intended for encrypting credit card transaction data. |
| Cloudreve is a self-hosted file management and sharing system. Prior to version 4.13.0, the application uses the weak pseudo-random number generator math/rand seeded with time.Now().UnixNano() to generate critical security secrets, including the secret_key, and hash_id_salt. These secrets are generated upon first startup and persisted in the database. An attacker can exploit this by obtaining the administrator's account creation time (via public API endpoints) to narrow the search window for the PRNG seed, and use known hashid to validate the seed. By brute-forcing the seed (demonstrated to take <3 hours on general consumer PC), an attacker can predict the secret_key. This allows them to forge valid JSON Web Tokens (JWTs) for any user, including administrators, leading to full account takeover and privilege escalation. This issue has been patched in version 4.13.0. |
| Cryptographic Flaw in PDFium in Google Chrome prior to 147.0.7727.55 allowed an attacker to read potentially sensitive information from encrypted PDFs via a brute-force attack. (Chromium security severity: Medium) |
| Auth0-PHP is a PHP SDK for Auth0 Authentication and Management APIs. From version 8.0.0 to before version 8.19.0, in applications built with the Auth0 PHP SDK, cookies are encrypted with insufficient entropy, which may result in threat actors brute-forcing the encryption key and forging session cookies. This issue has been patched in version 8.19.0. |
