CVE-2025-66565 1 Gofiber 1 Utils 2025-12-11 9.8 Critical
Fiber Utils is a collection of common functions created for Fiber. In versions 2.0.0-rc.3 and below, when the system's cryptographic random number generator (crypto/rand) fails, both functions silently fall back to returning predictable UUID values, including the zero UUID "00000000-0000-0000-0000-000000000000". The vulnerability occurs through two related but distinct failure paths, both ultimately caused by crypto/rand.Read() failures, compromising the security of all Fiber applications using these functions for security-critical operations. This issue is fixed in version 2.0.0-rc.4.
CVE-2025-67504 1 Wbce 1 Wbce Cms 2025-12-11 9.1 Critical
WBCE CMS is a content management system. Versions 1.6.4 and below use function GenerateRandomPassword() to create passwords using PHP's rand(). rand() is not cryptographically secure, which allows password sequences to be predicted or brute-forced. This can lead to user account compromise or privilege escalation if these passwords are used for new accounts or password resets. The vulnerability is fixed in version 1.6.5.
CVE-2024-57868 1 Lev 1 Web\ 2025-11-13 5.5 Medium
Web::API 2.8 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically Web::API uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
CVE-2024-52322 1 Localshop 1 Webservice\ 2025-11-13 5.5 Medium
WebService::Xero 0.11 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically WebService::Xero uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
CVE-2025-47781 1 Rallly 1 Rallly 2025-11-06 9.8 Critical
Rallly is an open-source scheduling and collaboration tool. Versions up to and including 3.22.1 of the application features token based authentication. When a user attempts to login to the application, they insert their email and a 6 digit code is sent to their email address to complete the authentication. A token that consists of 6 digits only presents weak entropy however and when coupled with no token brute force protection, makes it possible for an unauthenticated attacker with knowledge of a valid email address to successfully brute force the token within 15 minutes (token expiration time) and take over the account associated with the targeted email address. All users on the Rallly applications are impacted. As long as an attacker knows the user's email address they used to register on the app, they can systematically take over any user account. For the authentication mechanism to be safe, the token would need to be assigned a complex high entropy value that cannot be bruteforced within reasonable time, and ideally rate limiting the /api/auth/callback/email endpoint to further make brute force attempts unreasonable within the 15 minutes time. As of time of publication, no patched versions are available.
CVE-2023-49599 1 Wwbn 1 Avideo 2025-11-04 9.8 Critical
An insufficient entropy vulnerability exists in the salt generation functionality of WWBN AVideo dev master commit 15fed957fb. A specially crafted series of HTTP requests can lead to privilege escalation. An attacker can gather system information via HTTP requests and brute force the salt offline, leading to forging a legitimate password recovery code for the admin user.
CVE-2023-4344 1 Broadcom 1 Raid Controller Web Interface 2025-11-04 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-2024-47945 2 Rittal, Rittal Gmbh And Co.kg 5 Cmc Iii Processing Units, Cmc Iii Processing Units Firmware, Iot Interface and 2 more 2025-11-03 9.1 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-2024-58134 1 Mojolicious 1 Mojolicious 2025-10-20 8.1 High
Mojolicious versions from 0.999922 for Perl uses a hard coded string, or the application's class name, as an HMAC session cookie secret by default. These predictable default secrets can be exploited by an attacker to forge session cookies.  An attacker who knows or guesses the secret could compute valid HMAC signatures for the session cookie, allowing them to tamper with or hijack another user’s session.
CVE-2025-52464 1 Meshtastic 2 Firmware, Meshtastic Firmware 2025-10-09 8.3 High
Meshtastic is an open source mesh networking solution. In versions from 2.5.0 to before 2.6.11, the flashing procedure of several hardware vendors was resulting in duplicated public/private keys. Additionally, the Meshtastic was failing to properly initialize the internal randomness pool on some platforms, leading to possible low-entropy key generation. When users with an affected key pair sent Direct Messages, those message could be captured and decrypted by an attacker that has compiled the list of compromised keys. This issue has been patched in version 2.6.11 where key generation is delayed til the first time the LoRa region is set, along with warning users when a compromised key is detected. Version 2.6.12 furthers this patch by automatically wiping known compromised keys when found. A workaround to this vulnerability involves users doing a complete device wipe to remove vendor-cloned keys.
CVE-2025-1828 1 Timlegge 1 Crypt\ 2025-09-29 8.8 High
Crypt::Random Perl package 1.05 through 1.55 may use rand() function, which is not cryptographically strong, for cryptographic functions. If the Provider is not specified and /dev/urandom or an Entropy Gathering Daemon (egd) service is not available Crypt::Random will default to use the insecure Crypt::Random::rand provider. In particular, Windows versions of perl will encounter this issue by default.
CVE-2024-58036 1 Norbu09 1 Net\ 2025-09-29 5.5 Medium
Net::Dropbox::API 1.9 and earlier for Perl uses the rand() function as the default source of entropy, which is not cryptographically secure, for cryptographic functions. Specifically Net::Dropbox::API uses the Data::Random library which specifically states that it is "Useful mostly for test programs". Data::Random uses the rand() function.
CVE-2025-59015 1 Typo3 1 Typo3 2025-09-10 6.5 Medium

This vulnerability could allow an unauthenticated attacker to retrieve a private key by factoring the RSA modulus N in the certificate of the web administration interface.
CVE-2024-25407 1 Steve-community 1 Steve 2025-05-08 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-2024-25730 1 Hitrontech 4 Coda-4582u, Coda-4582u Firmware, Coda-4589 and 1 more 2025-05-05 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 2 Argoproj, Redhat 2 Argo Cd, Openshift Gitops 2025-04-23 8.3 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-2017-6030 1 Schneider-electric 6 Modicon M221, Modicon M221 Firmware, Modicon M241 and 3 more 2025-04-20 6.5 Medium
A Predictable Value Range from Previous Values issue was discovered in Schneider Electric Modicon PLCs Modicon M221, firmware versions prior to Version 1.5.0.0, Modicon M241, firmware versions prior to Version 4.0.5.11, and Modicon M251, firmware versions prior to Version 4.0.5.11. The affected products generate insufficiently random TCP initial sequence numbers that may allow an attacker to predict the numbers from previous values. This may allow an attacker to spoof or disrupt TCP connections.
