Vulnerabilidades

Con el objetivo de informar, advertir y ayudar a los profesionales sobre las ultimas vulnerabilidades de seguridad en sistemas tecnológicos, ponemos a disposición de los usuarios interesados en esta información una base de datos con información en castellano sobre cada una de las ultimas vulnerabilidades documentadas y conocidas.

Este repositorio con más de 75.000 registros esta basado en la información de NVD (https://nvd.nist.gov/) (National Vulnerability Database) – en función de un acuerdo de colaboración – por el cual desde INCIBE realizamos la traducción al castellano de la información incluida. En ocasiones este listado mostrará vulnerabilidades que aún no han sido traducidas debido a que se recogen en el transcurso del tiempo en el que el equipo de INCIBE realiza el proceso de traducción.

Se emplea el estándar de nomenclatura de vulnerabilidades CVE (https://cve.mitre.org/) (Common Vulnerabilities and Exposures), con el fin de facilitar el intercambio de información entre diferentes bases de datos y herramientas. Cada una de las vulnerabilidades recogidas enlaza a diversas fuentes de información así como a parches disponibles o soluciones aportadas por los fabricantes y desarrolladores. Es posible realizar búsquedas avanzadas teniendo la opción de seleccionar diferentes criterios como el tipo de vulnerabilidad, fabricante, tipo de impacto entre otros, con el fin de acortar los resultados.

Mediante suscripción RSS (https://www.incibe.es/feed/vulnerabilities) o Boletines (https://www.incibe.es/incibe/suscripciones) podemos estar informados diariamente de las ultimas vulnerabilidades incorporadas al repositorio.

CVE-2024-4393

Fecha de publicación:

*** Pendiente de traducción *** The Social Connect plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 1.2. This is due to insufficient verification on the OpenID server being supplied during the social login through the plugin. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email.

Severidad: CRÍTICA

CVE-2024-4418

Fecha de publicación:

*** Pendiente de traducción *** A race condition leading to a stack use-after-free flaw was found in libvirt. Due to a bad assumption in the virNetClientIOEventLoop() method, the `data` pointer to a stack-allocated virNetClientIOEventData structure ended up being used in the virNetClientIOEventFD callback while the data pointer&#39;s stack frame was concurrently being "freed" when returning from virNetClientIOEventLoop(). The &#39;virtproxyd&#39; daemon can be used to trigger requests. If libvirt is configured with fine-grained access control, this issue, in theory, allows a user to escape their otherwise limited access. This flaw allows a local, unprivileged user to access virtproxyd without authenticating. Remote users would need to authenticate before they could access it.

CVE-2024-1929

Fecha de publicación:

*** Pendiente de traducción *** Local Root Exploit via Configuration Dictionary in dnf5daemon-server before 5.1.17 allows a malicious user to impact Confidentiality and Integrity via Configuration Dictionary.<br /> <br /> There are issues with the D-Bus interface long before Polkit is invoked. The `org.rpm.dnf.v0.SessionManager.open_session` method takes a key/value map of configuration entries. A sub-entry in this map, placed under the "config" key, is another key/value map. The configuration values found in it will be forwarded as configuration overrides to the `libdnf5::Base` configuration. <br /> <br /> Practically all libdnf5 configuration aspects can be influenced here. Already when opening the session via D-Bus, the libdnf5 will be initialized using these override configuration values. There is no sanity checking of the content of this "config" map, which is untrusted data. It is possible to make the library loading a plug-in shared library under control of an unprivileged user, hence achieving root access. <br /> <br />

CVE-2024-1930

Fecha de publicación:

*** Pendiente de traducción *** No Limit on Number of Open Sessions / Bad Session Close Behaviour in dnf5daemon-server before 5.1.17 allows a malicious user to impact Availability via No Limit on Number of Open Sessions.<br /> <br /> There is no limit on how many sessions D-Bus clients may create using the `open_session()` D-Bus method. For each session a thread is created in dnf5daemon-server. This spends a couple of hundred megabytes of memory in the process. Further connections will become impossible, likely because no more threads can be spawned by the D-Bus service.<br /> <br />

CVE-2024-2746

Fecha de publicación:

*** Pendiente de traducción *** Incomplete fix for CVE-2024-1929<br /> <br /> The problem with CVE-2024-1929 was that the dnf5 D-Bus daemon accepted arbitrary configuration parameters from unprivileged users, which allowed a<br /> local root exploit by tricking the daemon into loading a user controlled "plugin". All of this happened before Polkit authentication was even started.<br /> <br /> The dnf5 library code does not check whether non-root users control the directory in question. <br /> <br /> On one hand, this poses a Denial-of-Service attack vector by making the daemonoperate on a blocking file (e.g. named FIFO special file) or a very large file<br /> that causes an out-of-memory situation (e.g. /dev/zero). On the other hand, this can be used to let the daemon process privileged files like /etc/shadow.<br /> The file in question is parsed as an INI file. Error diagnostics resulting from parsing privileged files could cause information leaks, if these diagnostics<br /> are accessible to unprivileged users. In the case of libdnf5, no such user accessible diagnostics should exist, though.<br /> <br /> Also, a local attacker can place a valid repository configuration file in this directory. This configuration file allows to specify<br /> a plethora of additional configuration options. This makes various additional code paths in libdnf5 accessible to the attacker. <br />

CVE-2023-35749

Fecha de publicación:

*** Pendiente de traducción *** D-Link DAP-2622 DDP Firmware Upgrade Filename Stack-based Buffer Overflow Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of D-Link DAP-2622 routers. Authentication is not required to exploit this vulnerability.<br /> <br /> The specific flaw exists within the DDP service. The issue results from the lack of proper validation of the length of user-supplied data prior to copying it to a fixed-length stack-based buffer. An attacker can leverage this vulnerability to execute code in the context of root. Was ZDI-CAN-20077.
