CVE-2009-4137
HighSummary
Funkcja loadContentFromCookie w pliku core/Cookie.php w Piwik przed wersją 0.5 nie weryfikuje ciągów uzyskanych z ciasteczek przed wywołaniem funkcji unserialize, co pozwala zdalnym atakującym na wykonanie dowolnego kodu lub przesyłanie dowolnych plików. Wykorzystanie tej podatności może odbywać się poprzez różne wektory związane z funkcjami __destruct w klasie Piwik_Config oraz innymi elementami Zend Framework i Smarty.
Risk Assessment
Podatność ta stwarza poważne ryzyko dla bezpieczeństwa aplikacji, umożliwiając atakującym zdalne wykonanie kodu, co może prowadzić do przejęcia kontroli nad systemem. Organizacje mogą być narażone na utratę danych oraz usunięcie lub modyfikację krytycznych plików.
Recommendation
Zaleca się aktualizację Piwik do najnowszej wersji, aby usunąć tę podatność. Dodatkowo, warto wdrożyć mechanizmy walidacji danych wejściowych z ciasteczek przed ich przetwarzaniem.

imgproxy from 4.0.0 before 4.0.16 contains an integer overflow in the ICO loader that allows remote attackers to trigger a heap buffer overflow via a crafted data_size value. Attackers can submit a crafted ICO image whose data_size wraps the allocation in vips/icoload.c, corrupting heap memory to crash the process or achieve code execution.
- CVE-2026-123551Critical
OpenAM from 14.0.0 before 16.1.4 contains an information disclosure vulnerability that allows unauthenticated attackers to read live session tokens from the notification WebSocket. Attackers can bypass the agent-only check through an unvalidated internal forward on legacy Liberty ID-FF endpoints, collecting iPlanetDirectoryPro tokens to hijack user and administrator sessions.
- CVE-2026-123550Critical
OpenAM before 16.1.4 contains an authentication bypass vulnerability in its SAML v2.0 service provider that accepts unsigned assertions on the ECP (PAOS) and HTTP-Artifact bindings when WantAssertionsSigned is false. Unauthenticated remote attackers can submit forged assertions to obtain sessions as any mapped user, including administrators, and hijack single sign-on to dependent applications.
- CVE-2026-123549Critical
OpenAM before 16.1.4 fails to enforce the Valid Creation Attributes list during self-registration, allowing anonymous attackers to set restricted attributes including group membership. Attackers can register through the legacy self-service REST endpoint or User Self-Service flow to join administrative groups and gain full administrative control of OpenAM.

- CVE-2026-123966Critical
A vulnerability was found in Tenda AC19 version 16.03.10.07 in the saveParentControlInfo function of the /goform/saveParentControlInfo file. Manipulating the deviceId argument causes a heap-based buffer overflow. The attack can be carried out remotely, and the exploit has been publicly disclosed.
- CVE-2026-120984Critical
A flaw was found in the Keycloak server's client management component. When a client is created or imported with authorization services enabled, the system fails to properly clear an internal session attribute used during setup. An authenticated attacker with client management permissions can bypass security controls and upload a malicious JavaScript policy that executes on the server.
Original NVD description (English source)
The loadContentFromCookie function in core/Cookie.php in Piwik before 0.5 does not validate strings obtained from cookies before calling the unserialize function, which allows remote attackers to execute arbitrary code or upload arbitrary files via vectors related to the __destruct function in the Piwik_Config class; php://filter URIs; the __destruct functions in Zend Framework, as demonstrated by the Zend_Log destructor; the shutdown functions in Zend Framework, as demonstrated by the Zend_Log_Writer_Mail class; the render function in the Piwik_View class; Smarty templates; and the _eval function in Smarty.
