CVE-2026-19565 2026-08-23 N/A
Apache::AppSamurai::Util versions through 1.01 for Perl generate predictable session authentication keys from the clock and process id in CreateSessionAuthKey. CreateSessionAuthKey runs five rounds of SHA-256, each over a fresh Time::HiRes reading formatted to six decimal places, the running digest, and the process id. CreateSession calls it with an empty key source on every login, and the optional Keysource directive is the only route to the other branch. The result is 64 hex characters. The microsecond field of the first reading takes one of a million values, the later readings follow it within microseconds, and the process id is drawn from a small range. The key is returned to the browser as the session cookie, and is combined with the configured server key to compute the session id and to encrypt the stored session data. An attacker who knows the second in which a session was created and the process id of the worker that created it can enumerate candidate keys and recover the victim's cookie, bypassing authentication for the protected resources. Each candidate has to be tried against the server, which validates the cookie with a key the attacker does not hold.
CVE-2026-15571 1 Redhat 8 Build Keycloak, Build Of Keycloak, Data Grid 8 and 5 more 2026-08-21 7.3 High
A flaw was found in the legacy client-initiated account-linking endpoint of Keycloak, a widely used open-source identity and access management solution. The mechanism used to protect the account-linking process from unauthorized requests relies on a hash that can be predicted by a malicious OIDC client. By tricking a user into authenticating, an attacker-controlled client can forge a valid linking URL to connect the victim's account to an attacker's external identity. This results in a full account takeover, allowing the attacker to log in as the victim.
CVE-2025-40780 1 Isc 1 Bind 9 2025-11-04 8.6 High
In specific circumstances, due to a weakness in the Pseudo Random Number Generator (PRNG) that is used, it is possible for an attacker to predict the source port and query ID that BIND will use. This issue affects BIND 9 versions 9.16.0 through 9.16.50, 9.18.0 through 9.18.39, 9.20.0 through 9.20.13, 9.21.0 through 9.21.12, 9.16.8-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.39-S1, and 9.20.9-S1 through 9.20.13-S1.
CVE-2025-42925 1 Sap 4 Java As, Netweaver, Netweaver Java and 1 more 2025-09-09 4.3 Medium
Due to the lack of randomness in assigning Object Identifiers in the SAP NetWeaver AS JAVA IIOP service, an authenticated attacker with low privileges could predict the identifiers by conducting a brute force search. By leveraging knowledge of several identifiers generated close to the same time, the attacker could determine a desired identifier which could enable them to access limited system information. This poses a low risk to confidentiality without impacting the integrity or availability of the service.
CVE-2025-48461 1 Advantech 6 Wise-4010lan, Wise-4010lan Firmware, Wise-4050lan and 3 more 2025-07-09 5 Medium
Successful exploitation of the vulnerability could allow an unauthenticated attacker to conduct brute force guessing and account takeover as the session cookies are predictable, potentially allowing the attackers to gain root, admin or user access and reset passwords.
CVE-2023-49259 1 Hongdian 2 H8951-4g-esp, H8951-4g-esp Firmware 2025-06-20 7.5 High
The authentication cookies are generated using an algorithm based on the username, hardcoded secret and the up-time, and can be guessed in a reasonable time.
CVE-2016-3672 4 Canonical, Linux, Novell and 1 more 11 Ubuntu Linux, Linux Kernel, Suse Linux Enterprise Desktop and 8 more 2025-04-12 N/A
The arch_pick_mmap_layout function in arch/x86/mm/mmap.c in the Linux kernel through 4.5.2 does not properly randomize the legacy base address, which makes it easier for local users to defeat the intended restrictions on the ADDR_NO_RANDOMIZE flag, and bypass the ASLR protection mechanism for a setuid or setgid program, by disabling stack-consumption resource limits.
CVE-2021-4277 1 Utils Project 1 Utils 2024-11-21 2.6 Low
A vulnerability, which was classified as problematic, has been found in fredsmith utils. This issue affects some unknown processing of the file screenshot_sync of the component Filename Handler. The manipulation leads to predictable from observable state. The name of the patch is dbab1b66955eeb3d76b34612b358307f5c4e3944. It is recommended to apply a patch to fix this issue. The identifier VDB-216749 was assigned to this vulnerability.
CVE-2020-5365 1 Dell 1 Emc Isilon Onefs 2024-11-21 5.3 Medium
Dell EMC Isilon versions 8.2.2 and earlier contain a remotesupport vulnerability. The pre-configured support account, remotesupport, is bundled in the Dell EMC Isilon OneFS installation. This account is used for diagnostics and other support functions. Although the default password is different for every cluster, it is predictable.
CVE-2020-1731 1 Redhat 1 Keycloak Operator 2024-11-21 9.1 Critical
A flaw was found in all versions of the Keycloak operator, before version 8.0.2,(community only) where the operator generates a random admin password when installing Keycloak, however the password remains the same when deployed to the same OpenShift namespace.
CVE-2019-6563 1 Moxa 8 Eds-405a, Eds-405a Firmware, Eds-408a and 5 more 2024-11-21 9.8 Critical
Moxa IKS and EDS generate a predictable cookie calculated with an MD5 hash, allowing an attacker to capture the administrator's password, which could lead to a full compromise of the device.
CVE-2019-11184 2 Intel, Netapp 482 3106, 3106 Firmware, 4109t and 479 more 2024-11-21 4.8 Medium
A race condition in specific microprocessors using Intel (R) DDIO cache allocation and RDMA may allow an authenticated user to potentially enable partial information disclosure via adjacent access.
CVE-2018-17917 1 Xiongmaitech 1 Xmeye P2p Cloud Server 2024-11-21 N/A
All versions of Hangzhou Xiongmai Technology Co., Ltd XMeye P2P Cloud Server may allow an attacker to use MAC addresses to enumerate potential Cloud IDs. Using this ID, the attacker can discover and connect to valid devices using one of the supported apps.
CVE-2024-10141 1 Jsbroks 1 Coco Annotator 2024-10-23 3.7 Low
A vulnerability, which was classified as problematic, was found in jsbroks COCO Annotator 0.11.1. This affects an unknown part of the component Session Handler. The manipulation of the argument SECRET_KEY leads to predictable from observable state. It is possible to initiate the attack remotely. The complexity of an attack is rather high. The exploitability is told to be difficult. The exploit has been disclosed to the public and may be used.
