VAR-200312-0239

Vulnerability from variot - Updated: 2025-04-03 22:19

Apple Safari 1.0 through 1.1 on Mac OS X 10.3.1 and Mac OS X 10.2.8 allows remote attackers to steal user cookies from another domain via a link with a hex-encoded null character (%00) followed by the target domain. An issue has been discovered in Apple Safari, which may allow an attacker to steal cookie-based authentication credentials from a user of a vulnerable web browser. The problem is in the handling of NULL (%00) characters in URLs. This issue may only be exploited to steal cookies set for a domain, as opposed to cookies set for a specific host in that domain. Cookies set with the secure flag can be stolen if the attacker uses SSL. Apple Safari is a WEB browser based on the Apple system. Remote attackers can exploit this vulnerability to construct malicious URLs, lure users to visit them, and steal sensitive cookie information. If the Apple Safari browser loads the following URL for resolution: http://alive.znep.com\%00www.passport.com/cgi-bin/cookies will cause the Apple Safari browser to connect to \"\%00\" before host, but sends the cookie to the server based on the entire hostname. This problem can be used to steal the cookie information of a specific path, and through the specific path and SSL in the request URL, it can also steal the cookie information that uses the secure mark

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.
