Title
Busybox: httpd password rule bypass for pre-compressed .gz files via accept-encoding: gzip
Summary
A flaw was found in BusyBox. When the HTTP daemon (httpd) has pre-compressed file support enabled, authentication checks are evaluated only against the requested URL path rather than the pre-compressed file being served. A remote attacker can exploit this flaw by requesting an uncompressed file path while specifying gzip encoding, bypassing password rules configured specifically for the compressed file. This vulnerability can lead to unauthorized information disclosure of sensitive files.

{

"value": "To mitigate this vulnerability without modifying binary features, apply one of the following configuration measures:\n\n1. Configure directory-level authentication:\nIn the BusyBox `httpd.conf` configuration file, define authentication rules covering the containing directory rather than individual file paths. Directory rules are evaluated against both the base request and served compressed variants.\n\n2. Protect base filenames:\nWhen individual file protection is necessary, configure password rules for both the uncompressed filename and the `.gz` filename (for example, applying the directive to both `/secret.txt` and `/secret.txt.gz`).\n\n3. Restrict service access:\nRestrict network reachability to the BusyBox httpd daemon using local firewall rules if remote access is not required.\n\nWarning: Applying changes to httpd.conf requires restarting or reloading the BusyBox httpd process, which will temporarily terminate active network sessions."

Experimental. This forecast is provided for visualization only and may change without notice. Do not use it for operational decisions.
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.

Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
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.
