VAR-200701-0518

Vulnerability from variot - Updated: 2026-03-09 22:42

The CFUserNotificationSendRequest function in UserNotificationCenter.app in Apple Mac OS X 10.4.8, when used in combination with diskutil, allows local users to gain privileges via a malicious InputManager in Library/InputManagers in a user's home directory, which is executed when Cocoa applications attempt to notify the user. Apple's UserNotificationCenter contains a vulnerability that may allow local users to gain elevated privileges. According to Apple's information, gaining elevated privileges could result in unauthorized overwriting or modification of system files. This issue stems from a flaw in the UserNotificationCenter application that results in arbitrary code-execution with wheel-group privileges. This issue affects Apple Mac OS X version 10.4.8; other versions may also be affected.


To improve our services to our customers, we have made a number of additions to the Secunia Advisories and have started translating the advisories to German.

The improvements will help our customers to get a better understanding of how we reached our conclusions, how it was rated, our thoughts on exploitation, attack vectors, and scenarios.

The vulnerability exists due to an error in the "fpathconf()" syscall when it is called with an unsupported file type and can be exploited to cause a system panic.

The vulnerability is confirmed in version 10.4.8. Other versions may also be affected.

SOLUTION: Grant only trusted users access to affected systems.

PROVIDED AND/OR DISCOVERED BY: Initially discovered in FreeBSD and reported in Mac OS X by Ilja Van Sprundel.

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.

    Related by attack behaviour

    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.
