PySaml2 v5.0.0 - Security release

by ivan.kanak＠gmail.com

Hello everyone, there has been a report on incident-response at idpy.org about a security issue in PySaml2. Alexey Sintsov and Yuri Goltsev from HERE Technologies reached out and reported a XML Signature Wrapping (XSW) vulnerability. The issue affects responses with signed assertions. PySaml2 can be tricked to think that an assertion had been signed and use the assertion information, when in reality the Signature points to another part of the xml document that is controlled by another party. The issue was assigned CVE-2020-5390 and is now fixed in the latest pysaml2 release. The relevant code commit that fixes is the issue: https://github.com/IdentityPython/pysaml2/commit/5e9d5acbcd8ae45c4e736ac521… Release v5.0.0 contains more changes, including: - Add freshness period feature for MetaDataMDX - Fix ipv6 validation to accommodate for addresses with brackets - Fix xmlsec temporary files deletions - Add method to get supported algorithms from metadata - Add mdstore method to extract assurance certifications - Add mdstore method to extract contact_person data - Start dropping python2 support Pointers to the release with changelog and more information, below: - the relevant release commit: https://github.com/IdentityPython/pysaml2/commit/f27c7e7a7010f83380566a219f… - the github release: https://github.com/IdentityPython/pysaml2/releases/tag/v5.0.0 - the pypi package: https://pypi.org/project/pysaml2/5.0.0/ + + + + + + + + In more detail, regarding the XSW vulnerability: libxml2 follows the xmldsig-core specification. The xmldsig specification is way too general. saml-core reuses the xmldsig specification, but constrains it to use of specific facilities. The implementation of the SAML specification is responsible to enforce those constraints. libxml2/xmlsec1 are not aware of those constraints and thus process the document based on the full/general xmldsig rules. What is happening is the following: - xmldsig-core allows the signature-information and the data that was signed to be in different places. This works by setting the URI attribute of the Reference element. The URI attribute contains an optional identifier of the object being signed. (see "4.4.3 The Reference Element" -- https://www.w3.org/TR/xmldsig-core1/#sec-Reference) This identifier is actually a pointer that can be defined in many different ways; from XPath expressions that need to be executed(!), to a full URL that should be fetched(!) in order to recalculate the signature. - saml-core section "5.4 XML Signature Profile" defines constrains on the xmldsig-core facilities. It explicitly dictates that enveloped signatures are the only signatures allowed. This mean that: * Assertion/RequestType/ResponseType elements must have an ID attribute * signatures must have a single Reference element * the Reference element must have a URI attribute * the URI attribute contains an anchor * the anchor points to the enclosing element's ID attribute xmlsec1 does the right thing - it follows the reference URI pointer and validates the assertion. But, the pointer points to an assertion in another part of the document; not the assertion in which the signature is embedded/enveloped. SAML processing thinks that the signature is fine (that's what xmlsec1 said), and gets the assertion data from the assertion that contains the signature - but that assertion was never validated. The issue is that pysaml2 does not enforce the constrains on the signature validation facilities of xmldsig-core, that the saml-core spec defines. The solution is simple; all we need is to make sure that assertions with signatures (1) contain one reference element that (2) has a URI attribute (3) that is an anchor that (4) points to the assertion in which the signature is embedded. If those conditions are met then we're good, otherwise we should fail the verification. -- Ivan c00kiemon5ter Kanakarakis >:3

Nominations now open - idpy Board

by hlflanagan＠sphericalcowgroup.com

Hola a todos! As described in the Statues of IdentityPython [1], roughly half the seats for the idpy Board are opening for nominations. The following members have completed their one-year terms: Ivan Kanakarakis (current chair) Mike Jones Chris Whalen Roland Hedberg (at-large) They are all eligible to be nominated again for a new board term. The term for these seats is now shifting to a two-year cycle, such that half the board will be up for nomination each year. Participants on the idpy-dev list act as the nominating committee for the idpy board. If you would like to nominate someone (or self-nominate) please contact me directly no later than 24 January 2020. Thank you for your time and consideration, Heather Flanagan [1] Excerpt from the Statutes of IdentityPython (https://dracc.commonsconservancy.org/0024/ <https://dracc.commonsconservancy.org/0024/>) Board of Directors The central decision-making body within IdentityPython is the IdentityPython Board of Directors (in short: the IdentityPython Board). The IdentityPython Board is a committee responsible for making and coordinating decisions on behalf of the user and developer community around IdentityPython, according to the conditions set forth in these Statutes as well as any Regulations established by prior decisions of the IdentityPython Board. The IdentityPython Board is expected to consult and find consensus for decisions with the user and developer community. The IdentityPython Board has a minimum of three, and a maximum of seven natural persons. The founding IdentityPython Board has appointed a number of its constituting Directors to serve a half (12 month) term, and the remainder to serve a regular (24 month) term. Subsequent Directors are elected by the IdentityPython Board to regular 24-month terms according to the procedure set out in these Statutes. The founding Board will select a nominating committee of active developers and other contributors to identify candidates for ongoing Board membership. Directors are permitted to seek office for multiple terms, however, when running against other candidates the amount of terms they have consecutively served is deducted from the votes cast in their favour. This provides a balance between continuity, equal opportunities and renewal of qualities and competences. The IdentityPython Board determines the Programme's structure and processes, and is responsible for maintaining its Statutes and Regulations. The IdentityPython Board is free to make or revise any decision, taking into consideration applicable law as well as any immutable conditions previously established within the Statutes or Regulations. In order to efficiently fulfill its tasks, the Board may establish specialized committees and task forces, as well as assign named roles to qualified individuals to provide advice and assistance on specific issues. The associated qualifications, tasks and responsibilities SHALL be formalised by publication as part of the Regulations of IdentityPython. The IdentityPython Board (and any person, group or organisation mandated by the IdentityPython Board on its behalf) must act in good faith and in the common interest of the developer community and the wider user community of IdentityPython. If significant harm to the organization has been committed by any Director, he or she MAY be removed from the Board by a simple majority vote of the rest of the Board. The IdentityPython Board SHALL convene offline or online at least every twelve (12) months.
