CVE-2018-14633 (GCVE-0-2018-14633)

Vulnerability from cvelistv5 – Published: 2018-09-25 00:00 – Updated: 2024-08-05 09:38

Summary
A security flaw was found in the chap_server_compute_md5() function in the ISCSI target code in the Linux kernel in a way an authentication request from an ISCSI initiator is processed. An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target's code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable.

An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target\u0027s code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable."

Un atacante remoto no autenticado puede provocar un desbordamiento de b\u00fafer basado en pila y quebrar hasta 17 bytes de la pila. El ataque requiere que el iSCSI objetivo est\u00e9 habilitado en el host de la v\u00edctima. Dependiendo de c\u00f3mo se haya construido el c\u00f3digo del objetivo (dependiendo de un compilador, marcas de compilaci\u00f3n o arquitectura del hardware), un ataque podr\u00eda conducir a un cierre inesperado del sistema y, por lo tanto, a una denegaci\u00f3n de servicio (DoS) o, posiblemente, a un acceso no autorizado a los datos exportados por un objetivo iSCSI. Debido a la naturaleza del error, no se puede descartar totalmente un escalado de privilegios, aunque se cree que es altamente improbable.

An unauthenticated remote attacker can cause a stack buffer overflow and smash up to 17 bytes of the stack. The attack requires the iSCSI target to be enabled on the victim host. Depending on how the target\u0027s code was built (i.e. depending on a compiler, compile flags and hardware architecture) an attack may lead to a system crash and thus to a denial-of-service or possibly to a non-authorized access to data exported by an iSCSI target. Due to the nature of the flaw, privilege escalation cannot be fully ruled out, although we believe it is highly unlikely. Kernel versions 4.18.x, 4.14.x and 3.10.x are believed to be vulnerable."

Un atacante remoto no autenticado puede provocar un desbordamiento de b\u00fafer basado en pila y quebrar hasta 17 bytes de la pila. El ataque requiere que el iSCSI objetivo est\u00e9 habilitado en el host de la v\u00edctima. Dependiendo de c\u00f3mo se haya construido el c\u00f3digo del objetivo (dependiendo de un compilador, marcas de compilaci\u00f3n o arquitectura del hardware), un ataque podr\u00eda conducir a un cierre inesperado del sistema y, por lo tanto, a una denegaci\u00f3n de servicio (DoS) o, posiblemente, a un acceso no autorizado a los datos exportados por un objetivo iSCSI. Debido a la naturaleza del error, no se puede descartar totalmente un escalado de privilegios, aunque se cree que es altamente improbable.

Taxonomy of the tags.




Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

Nomenclature

  • Seen: The vulnerability was mentioned, discussed, or observed by the user.
  • Confirmed: The vulnerability has been validated from an analyst's perspective.
  • Published Proof of Concept: A public proof of concept is available for this vulnerability.
  • Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
  • Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
  • Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
  • Not confirmed: The user expressed doubt about the validity of the vulnerability.
  • Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

    Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
