Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Konqueror can associate a cookie with multiple domains when the DNS resolver has a non-root domain in its search list, which allows remote attackers to trick a user into accepting a cookie for a hostname formed via search-list expansion of the hostname entered by the user, or steal a cookie for an expanded hostname, as demonstrated by an attacker who operates an ap1.com Internet web site to steal cookies associated with an ap1.com.example.com intranet web site.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

Konqueror incorrectly associates cookies with multiple domains when the DNS resolver has a non-root domain in its search list. This allows remote attackers to steal cookies for expanded hostnames (e.g., an attacker at ap1.com can steal cookies meant for ap1.com.example.com) by exploiting DNS search-list expansion ambiguity in cookie domain validation.

MitigationAvoid using DNS search lists with ambiguous domain suffixes, or ensure users do not browse untrusted external sites while their DNS resolver is configured with internal domain suffixes that could be expanded.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify Konqueror version
    Run 'konqueror --version' or check your package manager for installed kdebase or konqueror package version
    Affected if The installed version matches any of these: 0.1, 2.1.1, 2.1.2, 2.2.1, 2.2.2, 3.0, 3.0.1, 3.0.2, 3.0.3, 3.0.5, 3.0.5b, or 3.1
  2. Check DNS resolver search list configuration
    Inspect /etc/resolv.conf and look for 'search' directives, or run 'nmcli dev show | grep DOMAIN' or 'systemd-resolve --status' depending on your system
    Affected if A 'search' line contains one or more domain suffixes (non-root domains) in the DNS configuration
  3. Verify if browsing occurs to untrusted external sites
    Review user browsing habits or network proxy configurations to determine if Konqueror is used to access external untrusted websites
    Affected if Users browse untrusted external websites while their DNS resolver search list includes internal domain suffixes that could be expanded

You are affected if Konqueror version is one of the listed versions AND your DNS resolver has a search list with domain suffixes, AND users browse untrusted external sites under these conditions.
