NASL family Ubuntu Local Security Checks NASL id UBUNTU_USN-3257-1.NASL description A large number of security issues were discovered in the WebKitGTK+ Web and JavaScript engines. If a user were tricked into viewing a malicious website, a remote attacker could exploit a variety of issues related to web browser security, including cross-site scripting attacks, denial of service attacks, and arbitrary code execution. Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory.

It is, therefore, affected by multiple vulnerabilities: - An out-of-bounds read error exists in WebKit when handling certain JavaScript code. An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the disclosure of memory contents. (CVE-2016-9642) - A denial of service vulnerability exists in WebKit when handling certain regular expressions. An unauthenticated, remote attacker can exploit this, via a specially crafted web page, to exhaust available memory resources. (CVE-2016-9643) - Multiple information disclosure vulnerabilities exist in WebKit when handling page loading due to improper validation of certain input. An unauthenticated, remote attacker can exploit these to disclose data cross-origin. (CVE-2017-2364, CVE-2017-2367) - An unspecified state management flaw exists that allows an unauthenticated, remote attacker to spoof the address bar. (CVE-2017-2376) - A denial of service vulnerability exists in the Web Inspector component when closing a window while the debugger is paused. An unauthenticated, remote attacker can exploit this to terminate the application. (CVE-2017-2377) - An unspecified flaw exists in WebKit when creating bookmarks using drag-and-drop due to improper validation of certain input. An unauthenticated, remote attacker can exploit this, via a specially crafted link, to spoof bookmarks or potentially execute arbitrary code. (CVE-2017-2378) - An information disclosure vulnerability exists in the Login AutofFill component that allows a local attacker to access keychain items. (CVE-2017-2385) - Multiple information disclosure vulnerabilities exist in WebKit when handling unspecified exceptions or elements. An unauthenticated, remote attacker can exploit these, via specially crafted web content, to disclose data cross-origin. (CVE-2017-2386, CVE-2017-2479, CVE-2017-2480) - An unspecified flaw exists in the handling of HTTP authentication that allows an unauthenticated, remote attacker to disclose authentication sheets on arbitrary websites or cause a denial of service condition.

An unauthenticated, remote attacker can exploit this to cause a denial of service condition or the execution of arbitrary code. (CVE-2017-2405) - An unspecified type confusion error exists that allows an unauthenticated remote attacker to execute arbitrary code by using specially crafted web content. (CVE-2017-2415) - A security bypass vulnerability exists in WebKit that allows an unauthenticated, remote attacker to bypass the Content Security Policy by using specially crafted web content. (CVE-2017-2419) - An unspecified flaw exists in WebKit when handling OpenGL shaders that allows an unauthenticated, remote attacker to disclose process memory content by using specially crafted web content. (CVE-2017-2424) - An information disclosure vulnerability exists in WebKit JavaScript Bindings when handling page loading due to unspecified logic flaws. An unauthenticated, remote attacker can exploit this, via specially crafted web content, to disclose data cross-origin. (CVE-2017-2442) - A memory corruption issue exists in WebKit within the CoreGraphics component due to improper validation of certain input. An unauthenticated, remote attacker can exploit this, via specially crafted web content, to cause a denial of service condition or the execution of arbitrary code.

description | ### Summary An exploitable information leak vulnerability exists in the Content Security Policy enforcement functionality of Microsoft Edge 40.15063.0.0. A specially crafted web page can cause a content security policy bypass resulting in an information leak. An attacker can create a malicious webpage to trigger this vulnerability. ### Tested Versions Microsoft Edge 40.15063.0.0 ### Product URLs https://www.microsoft.com/en-us/windows/microsoft-edge ### CVSSv3 Score 4.3 - CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N ### CWE CWE-284: Improper Access Control ### Details An attacker can bypass the Content-Security-Policy header that is used to make the browser protect against information leakage from a web site. By loading a new document using window.open("","_blank") and document.write-ing into it, (being in about:blank) an attacker can circumvent the CSP restrictions put on the document that the original page's Javascript code was running on and reach out to other sites. One could argue that the code was loaded with unsafe-inline in the CSP header, but that should still block any cross-site communication (e.g. 1x1px tracking image etc). The about:blank page has the same origin as its loading document, but CSP restrictions have been removed. The spec is pretty explicit that the CSP restrictions should be inherited: `https://w3c.github.io/webappsec-csp/#initialize-document-csp`. Tests show that e.g. Firefox does not show this behavior, but rather makes the new document inherit CSP from its loading document. This vulnerability was also present in Apple Safari (CVE-2017-2419) and Google Chrome (CVE-2017-5033) and was corrected there. ### Timeline * 2016-11-29 - Initial vendor contact by Nicolai * 2016-12-01 - Vendor confirms receipt * 2017-01-04 - Follow up with Vendor * 2017-01-04 - Vendor confirms reproduction * 2017-03-06 - Follow up with Vendor * 2017-03-07 - Vendor says this is by design and does not consider it a vulnerability * 2017-03-07 - More information provided to vendor * 2017-03-29 - Talos involvement, asks vendor to reconsider * 2017-06-06 - Follow up with vendor * 2017-06-07 - Vendor reopens case to reconsider * 2017-08-22 - Vendor informed about pending release date * 2017-09-06 - Public Release ### CREDIT * Discovered by Nicolai Grødum of Cisco. |
