PT-2025-40946

Name of the Vulnerable Software and Affected Versions YoSmart YoLink MQTT broker versions through 2025-10-02 Description The YoLink MQTT broker does not adequately enforce authorization controls, which can lead to cross-account attacks. An attacker who obtains device IDs can remotely operate...

CVE-2025-59449

The YoSmart YoLink MQTT broker through 2025-10-02 does not enforce sufficient authorization controls to prevent cross-account attacks, allowing an attacker to remotely operate affected devices if the attacker obtains the associated device IDs. Because YoLink device IDs are predictable, an attacke...

CVE-2025-40925: Generation of Predictable Numbers or Identifiers

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...

Generation of Predictable Numbers or Identifiers

Overview Affected versions of this package are vulnerable to Generation of Predictable Numbers or Identifiers via the websocket component due to using a fixed 32 bit mask that persisted and was used throughout the entire connection instead of updating it for each new outgoing frame as the...

CVE-2025-10148: Generation of Predictable Numbers or Identifiers

curl's WebSocket code did not update the 32-bit mask pattern for each new outgoing frame as the specification says. Instead it used a fixed mask that persisted and was used throughout the entire connection. A predictable mask pattern allows for a malicious server to induce traffic between the two...

CVE-2025-42925 Predictable Object Identifier vulnerability in SAP NetWeaver AS Java (IIOP Service)

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,...

CVE-2025-42925

The CVE-2025-42925 entry describes a vulnerability in SAP NetWeaver AS JAVA IIOP service caused by insufficient randomness when assigning Object Identifiers, enabling an authenticated lower-privileged actor to brute-force and predict identifiers to access limited system information. Affected comp...

Linux Distros Unpatched Vulnerability : CVE-2025-40924

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - 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...

CVE-2025-40920: Generation of Predictable Numbers or Identifiers

Catalyst::Authentication::Credential::HTTP versions 1.018 and earlier for Perl generate nonces using the Perl Data::UUID library. Data::UUID does not use a strong cryptographic source for generating UUIDs. Data::UUID returns v3 UUIDs, which are generated from known information and are unsuitable...

CVE-2025-40919: Generation of Predictable Numbers or Identifiers

Authen::DigestMD5 versions 0.01 through 0.02 for Perl generate the cnonce insecurely. The cnonce client nonce is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. The PID will come from a small set of numbers, and the epoch time may be guessed, if it is not...

CVE-2025-40918: Generation of Predictable Numbers or Identifiers

Authen::SASL::Perl::DIGESTMD5 versions 2.04 through 2.1800 for Perl generates the cnonce insecurely. The cnonce client nonce is generated from an MD5 hash of the PID, the epoch time and the built-in rand function. The PID will come from a small set of numbers, and the epoch time may be guessed, i...
