CVE-2008-2108 4 Canonical, Debian, Fedoraproject and 1 more 4 Ubuntu Linux, Debian Linux, Fedora and 1 more 2024-11-21 7.5 HIGH 9.8 CRITICAL
The GENERATE_SEED macro in PHP 4.x before 4.4.8 and 5.x before 5.2.5, when running on 64-bit systems, performs a multiplication that generates a portion of zero bits during conversion due to insufficient precision, which produces 24 bits of entropy and simplifies brute force attacks against protection mechanisms that use the rand and mt_rand functions.
CVE-2008-1447 6 Canonical, Cisco, Debian and 3 more 8 Ubuntu Linux, Ios, Debian Linux and 5 more 2024-11-21 5.0 MEDIUM 6.8 MEDIUM
The DNS protocol, as implemented in (1) BIND 8 and 9 before 9.5.0-P1, 9.4.2-P1, and 9.3.5-P1; (2) Microsoft DNS in Windows 2000 SP4, XP SP2 and SP3, and Server 2003 SP1 and SP2; and other implementations allow remote attackers to spoof DNS traffic via a birthday attack that uses in-bailiwick referrals to conduct cache poisoning against recursive resolvers, related to insufficient randomness of DNS transaction IDs and source ports, aka "DNS Insufficient Socket Entropy Vulnerability" or "the Kaminsky bug."
CVE-2001-0950 1 Valicert 1 Enterprise Validation Authority 2024-11-20 7.5 HIGH 7.5 HIGH
ValiCert Enterprise Validation Authority (EVA) Administration Server 3.3 through 4.2.1 uses insufficiently random data to (1) generate session tokens for HSMs using the C rand function, or (2) generate certificates or keys using /dev/urandom instead of another source which blocks when the entropy pool is low, which could make it easier for local or remote attackers to steal tokens or certificates via brute force guessing.
CVE-2024-26329 2024-11-14 N/A 6.2 MEDIUM
Chilkat before v9.5.0.98, allows attackers to obtain sensitive information via predictable PRNG in ChilkatRand::randomBytes function.
CVE-2024-20331 1 Cisco 2 Adaptive Security Appliance Software, Firepower Threat Defense Software 2024-11-01 N/A 5.9 MEDIUM
A vulnerability in the session authentication functionality of the Remote Access SSL VPN feature of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to prevent users from authenticating. This vulnerability is due to insufficient entropy in the authentication process. An attacker could exploit this vulnerability by determining the handle of an authenticating user and using it to terminate their authentication session. A successful exploit could allow the attacker to force a user to restart the authentication process, preventing a legitimate user from establishing remote access VPN sessions.
CVE-2024-6508 2024-10-30 N/A 8.0 HIGH
An insufficient entropy vulnerability was found in the Openshift Console. In the authorization code type and implicit grant type, the OAuth2 protocol is vulnerable to a Cross-Site Request Forgery (CSRF) attack if the state parameter is used inefficiently. This flaw allows logging into the victim’s current application account using a third-party account without any restrictions.
CVE-2023-37822 1 Eufy 2 Homebase 2, Homebase 2 Firmware 2024-10-29 N/A 8.2 HIGH
The Eufy Homebase 2 before firmware version 3.3.4.1h creates a dedicated wireless network for its ecosystem, which serves as a proxy to the end user's primary network. The WPA2-PSK generation of this dedicated network is flawed and solely based on the serial number. Due to the flawed generation process, the WPA2-PSK can be brute forced offline within seconds. This vulnerability allows an attacker in proximity to the dedicated wireless network to gain unauthorized access to the end user's primary network. The only requirement of the attack is proximity to the dedicated wireless network.
CVE-2024-47945 1 Rittal 4 Cmc Iii Processing Units, Cmc Iii Processing Units Firmware, Iot Interface and 1 more 2024-10-21 N/A 9.8 CRITICAL
The devices are vulnerable to session hijacking due to insufficient entropy in its session ID generation algorithm. The session IDs are predictable, with only 32,768 possible values per user, which allows attackers to pre-generate valid session IDs, leading to unauthorized access to user sessions. This is not only due to the use of an (insecure) rand() function call but also because of missing initialization via srand(). As a result only the PIDs are effectively used as seed.
CVE-2024-25407 1 Steve Project 1 Steve 2024-10-16 N/A 7.5 HIGH
SteVe v3.6.0 was discovered to use predictable transaction ID's when receiving a StartTransaction request. This vulnerability can allow attackers to cause a Denial of Service (DoS) by using the predicted transaction ID's to terminate other transactions.
CVE-2023-4344 1 Broadcom 1 Raid Controller Web Interface 2024-10-08 N/A 9.8 CRITICAL
Broadcom RAID Controller web interface is vulnerable to insufficient randomness due to improper use of ssl.rnd to setup CIM connection
CVE-2024-8796 1 Tinfoilsecurity 1 Devise-two-factor 2024-09-30 N/A 5.3 MEDIUM
Under the default configuration, Devise-Two-Factor versions >= 2.2.0 & < 6.0.0 generate TOTP shared secrets that are 120 bits instead of the 128-bit minimum defined by RFC 4226. Using a shared secret shorter than the minimum to generate a multi-factor authentication code could make it easier for an attacker to guess the shared secret and generate valid TOTP codes.
CVE-2024-22473 2024-09-27 N/A 6.8 MEDIUM
TRNG is used before initialization by ECDSA signing driver when exiting EM2/EM3 on Virtual Secure Vault (VSE) devices. This defect may allow Signature Spoofing by Key Recreation.This issue affects Gecko SDK through v4.4.0.
CVE-2024-38270 1 Zyxel 20 Gs1900-10hp, Gs1900-10hp Firmware, Gs1900-16 and 17 more 2024-09-18 N/A 6.5 MEDIUM
An insufficient entropy vulnerability caused by the improper use of a randomness function with low entropy for web authentication tokens generation exists in the Zyxel GS1900-10HP firmware version V2.80(AAZI.0)C0. This vulnerability could allow a LAN-based attacker a slight chance to gain a valid session token if multiple authenticated sessions are alive.
CVE-2024-25730 2024-08-16 N/A 9.8 CRITICAL
Hitron CODA-4582 and CODA-4589 devices have default PSKs that are generated from 5-digit hex values concatenated with a "Hitron" substring, resulting in insufficient entropy (only about one million possibilities).
CVE-2022-31034 1 Argoproj 1 Argo Cd 2024-08-07 6.8 MEDIUM 8.1 HIGH
Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting with v0.11.0 are vulnerable to a variety of attacks when an SSO login is initiated from the Argo CD CLI or UI. The vulnerabilities are due to the use of insufficiently random values in parameters in Oauth2/OIDC login flows. In each case, using a relatively-predictable (time-based) seed in a non-cryptographically-secure pseudo-random number generator made the parameter less random than required by the relevant spec or by general best practices. In some cases, using too short a value made the entropy even less sufficient. The attacks on login flows which are meant to be mitigated by these parameters are difficult to accomplish but can have a high impact potentially granting an attacker admin access to Argo CD. Patches for this vulnerability has been released in the following Argo CD versions: v2.4.1, v2.3.5, v2.2.10 and v2.1.16. There are no known workarounds for this vulnerability.
CVE-2023-49927 1 Samsung 26 Exynos 1080, Exynos 1080 Firmware, Exynos 1280 and 23 more 2024-08-01 N/A 5.3 MEDIUM
An issue was discovered in Samsung Mobile Processor, Wearable Processor, and Modem Exynos 980, Exynos 990, Exynos 850, Exynos 1080, Exynos 2100, Exynos 2200, Exynos 1280, Exynos 1380, Exynos 1330, Exynos 9110, Exynos W920, Exynos Modem 5123, Exynos Modem 5300. The baseband software does not properly check format types specified by the RRC. This can lead to a lack of encryption.
CVE-2024-36400 1 Viz 1 Nano Id 2024-06-10 N/A 9.8 CRITICAL
nano-id is a unique string ID generator for Rust. Affected versions of the nano-id crate incorrectly generated IDs using a reduced character set in the `nano_id::base62` and `nano_id::base58` functions. Specifically, the `base62` function used a character set of 32 symbols instead of the intended 62 symbols, and the `base58` function used a character set of 16 symbols instead of the intended 58 symbols. Additionally, the `nano_id::gen` macro is also affected when a custom character set that is not a power of 2 in size is specified. It should be noted that `nano_id::base64` is not affected by this vulnerability. This can result in a significant reduction in entropy, making the generated IDs predictable and vulnerable to brute-force attacks when the IDs are used in security-sensitive contexts such as session tokens or unique identifiers. The vulnerability is fixed in 0.4.0.
CVE-2023-46648 1 Github 1 Enterprise Server 2024-02-05 N/A 7.5 HIGH
An insufficient entropy vulnerability was identified in GitHub Enterprise Server (GHES) that allowed an attacker to brute force a user invitation to the GHES Management Console. To exploit this vulnerability, an attacker would need knowledge that a user invitation was pending. This vulnerability affected all versions of GitHub Enterprise Server since 3.8 and was fixed in version 3.8.12, 3.9.7, 3.10.4, and 3.11.1. This vulnerability was reported via the GitHub Bug Bounty program.
CVE-2023-26154 1 Pubnub 4 C-core, Kotlin, Pubnub and 1 more 2024-02-05 N/A 5.9 MEDIUM
Versions of the package pubnub before 7.4.0; all versions of the package com.pubnub:pubnub; versions of the package pubnub before 6.19.0; all versions of the package github.com/pubnub/go; versions of the package github.com/pubnub/go/v7 before 7.2.0; versions of the package pubnub before 7.3.0; versions of the package pubnub/pubnub before 6.1.0; versions of the package pubnub before 5.3.0; versions of the package pubnub before 0.4.0; versions of the package pubnub/c-core before 4.5.0; versions of the package com.pubnub:pubnub-kotlin before 7.7.0; versions of the package pubnub/swift before 6.2.0; versions of the package pubnub before 5.2.0; versions of the package pubnub before 4.3.0 are vulnerable to Insufficient Entropy via the getKey function, due to inefficient implementation of the AES-256-CBC cryptographic algorithm. The provided encrypt function is less secure when hex encoding and trimming are applied, leaving half of the bits in the key always the same for every encoded message or file. **Note:** In order to exploit this vulnerability, the attacker needs to invest resources in preparing the attack and brute-force the encryption.
