Vulnerability from csaf_redhat - Published: 2004-09-07 15:40 - Updated: 2024-11-21 23:08
Summary
Red Hat Security Advisory: mod_ssl security update
Severity
Important
Notes
Topic: An updated mod_ssl package for Apache that fixes a format string vulnerability is now available.
Details: The mod_ssl module provides strong cryptography for the Apache Web server via the Secure Sockets Layer (SSL) and Transport Layer Security (TLS) protocols. A format string issue was discovered in mod_ssl for Apache 1.3 which can be triggered if mod_ssl is configured to allow a client to proxy to remote SSL sites. In order to exploit this issue, a user who is authorized to use Apache as a proxy would have to attempt to connect to a carefully crafted hostname via SSL. The Common Vulnerabilities and Exposures project (cve.mitre.org) has assigned the name CAN-2004-0700 to this issue. Users of mod_ssl should upgrade to this updated package, which contains a backported patch to correct this issue.

CVE-2004-0700

Format string vulnerability in the mod_proxy hook functions function in ssl_engine_log.c in mod_ssl before 2.8.19 for Apache before 1.3.31 may allow remote attackers to execute arbitrary messages via format string specifiers in certain log messages for HTTPS that are handled by the ssl_log function.

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.
