The Unprll Project Vulnerability Response Process

NOTE

This document is incomplete and sections may not be accurate. Contact directly in case this document is incomplete on discovery of a vulnerability.

Preamble (Unprll)

  1. This Vulnerability Response Process and subsequent bounty reward apply to the following:

    • Code implementation as seen in the Unprll Project GitHub repositories
      • This includes code in all branches; including the master branch and any release branch

  2. Researchers/Hackers: while you research/hack, we ask that you please refrain from committing the following:

    • Denial of Service / Active exploiting against the Unprll network
    • Social Engineering of Unprll Project staff or contractors
    • Any physical or electronic attempts against Unprll community property and/or data centers

  3. As a pro-privacy project we have volunteers running copies of the websites on hidden services on Tor and I2P, as well as on multiple public domains. The live sites are NOT in the scope of this process; only the code is!

  4. Bounty will be released for all projects in Unprll ULL only. For more information on how to use Unprll, visit the Unprll website

  5. Bounty is not eligible to those who:

    • do not abide by the VRP for responsible disclosure
    • do not allow the completion of VRP points I through IV

Preamble (Unprll)

  1. Attacks which require more than 50% of the network hash rate to execute are out of policy scope

I. Points of contact for security issues

Unprll

ctobias [at] gmx.com
PGP fingerprint = D27D 7701 EC78 F359 C357 41B1 EC04 AE20 8EC2 9053
If pasting GPG encrypted data, use fpaste.org or pastebin.mozilla.org
or paste.debian.net as these don't blackball Tor via Cloudflare.

II. Security response team

  • TBD

III. Incident response

  1. Researcher submits report via one or both of two methods:

    • a. PGP encrypted Email (use the appropriate fingerprints listed in section I or as included in the Unprll repo in utils/gpg_keys/)

  2. Response Team designates a Response Manager who is in charge of the particular report based on availability and/or knowledge-set

  3. In no more than 3 working days, Response Team should gratefully respond to researcher using only encrypted, secure channels

  4. Response Manager makes inquiries to satisfy any needed information to confirm if submission is indeed a vulnerability

    • a. If submission proves to be vulnerable with PoC code / exploit, proceed to next step
    • b. If not vulnerable:
      • i. Response Manager responds with reasons why submission is not a vulnerability
      • ii. Response Manager moves discussion to a new or existing ticket on GitHub if necessary

  5. Establish severity of vulnerability:

    • a. HIGH: impacts network as a whole, has potential to break entire unprll network, results in the loss of unprll, or is on a scale of great catastrophe
    • b. MEDIUM: impacts individual nodes, routers, wallets, or must be carefully exploited
    • c. LOW: is not easily exploitable or is low impact
    • d. If there are any disputes regarding bug severity, the Unprll Response team will ultimately define bug severity

  6. Respond according to the severity of the vulnerability:

    • a. HIGH severities must be notified on website and reddit /r/Unprll within 3 working days of classification
      • i. The notification should list appropriate steps for users to take, if any
      • ii. The notification must not include any details that could suggest an exploitation path
      • iii. The latter takes precedence over the former
    • b. MEDIUM and HIGH severities will require a Point Release
    • c. LOW severities will be addressed in the next Regular Release

  7. Response Team applies appropriate patch(es)

    • a. Response Manager designates a PRIVATE git "hotfix branch" to work in
    • b. Patches are reviewed with the researcher
    • c. Any messages associated with PUBLIC commits during the time of review should not make reference to the security nature of the PRIVATE branch or its commits
    • d. Vulnerability announcement is drafted
      • i. Include the severity of the vulnerability
      • ii. Include all vulnerable systems/apps/code
      • iii. Include solutions (if any) if patch cannot be applied
    • e. Release date is discussed

  8. At release date, Response Team coordinates with developers to finalize update:

    • a. Response Manager propagates the "hotfix branch" to trunk
    • b. Response Manager includes vulnerability announcement draft in release notes
    • c. Proceed with the Point or Regular Release

IV. Post-release disclosure process

  1. Response Team has 90 days to fulfill all points within section III

  2. If the Incident Response process in section III is successfully completed:

    • a. Researcher decides whether or not to opt out of receiving name/handle/organization credit. By default, the researcher will receive name/handle/organization credit.
      • i. If bounty is applicable, release bounty to the researcher as defined in section "Bounty Distribution"
    • b. Finalize vulnerability announcement draft and include the following:
      • i. Project name and URL
      • ii. Versions known to be affected
      • iii. Versions known to be not affected (for example, the vulnerable code was introduced in a recent version, and older versions are therefore unaffected)
      • iv. Versions not checked
      • v. Type of vulnerability and its impact
      • vi. If already obtained or applicable, a CVE-ID
      • vii. The planned, coordinated release date
      • viii. Mitigating factors (for example, the vulnerability is only exposed in uncommon, non-default configurations)
      • ix. Workarounds (configuration changes users can make to reduce their exposure to the vulnerability)
      • x. If applicable, credits to the original reporter
    • c. Release finalized vulnerability announcement on website and reddit /r/Unprll
    • d. For HIGH severities, release finalized vulnerability announcement on well-known mailing lists:
    • e. If applicable, developers request a CVE-ID
      • i. The commit that applied the fix is made reference too in a future commit and includes a CVE-ID

  3. If the Incident Response process in section III is not successfully completed:

    • a. Response Team and developers organize an IRC meeting to discuss why/what points in section III were not resolved and how the team can resolve them in the future
    • b. Any developer meetings immediately following the incident should include points made in section V
    • c. If disputes arise about whether or when to disclose information about a vulnerability, the Response Team will publicly discuss the issue via IRC and attempt to reach consensus
    • d. If consensus on a timely disclosure is not met (no later than 90 days), the researcher (after 90 days) has every right to expose the vulnerability to the public

V. Bounty distribution

  • ULL for vulnerability-related bounties are solely contributed by community donators and escrowed by unpaid volunteers. Total availability of ULL contributed for bounties can be tracked here. ULL market values can be found at the various exchanges. See also Cryptowatch and Live Coin Watch.
  • As reports come in and payouts are made, the total bounty supply shrinks. This gives incentive for bug hunters to report bugs a.s.a.p.
  • The following percentages apply to available ULL bounty (severity is defined above in section III. 6.):
    1. 10% reserved for LOW severity bugs
    2. 30% reserved for MEDIUM severity bugs
    3. 60% for HIGH severity bugs
  • Each bug will at most receive 10% of each category. Example: 10% of 60% for a HIGH severity bug.

VI. Incident analysis

  1. Isolate codebase

    • a. Response Team and developers should coordinate to work on the following:
      • i. Problematic implementation of classes/libraries/functions, etc.
      • ii. Focus on apps/distro packaging, etc.
      • iii. Operator/config error, etc.

  2. Auditing

    • a. Response Team and developers should coordinate to work on the following:
      • i. Auditing of problem area(s) as discussed in point 1
      • ii. Generate internal reports and store for future reference
      • iii. If results are not sensitive, share with the public via IRC or GitHub

  3. Response Team has 45 days following completion of section III to ensure completion of section V

VII. Resolutions

Any further questions or resolutions regarding the incident(s) between the researcher and response + development team after public disclosure can be addressed via the following:

VIII. Continuous improvement

  1. Response Team and developers should hold annual meetings to review the previous year's incidents

  2. Response Team or designated person(s) should give a brief presentation, including:

    • a. Areas of Unprll affected by the incidents
    • b. Any network downtime or monetary cost (if any) of the incidents
    • c. Ways in which the incidents could have been avoided (if any)
    • d. How effective this process was in dealing with the incidents

  3. After the presentation, Response Team and developers should discuss:

    • a. Potential changes to development processes to reduce future incidents
    • b. Potential changes to this process to improve future responses
