CVSS v3.1 |
| Unspecified "drag-and-drop vulnerability" in Opera Web Browser before 8.50 on Windows allows "unintentional file uploads." |
| Opera 8.50 allows remote attackers to cause a denial of service (crash) via a Java applet with a large string argument to the removeMember JNI method for the com.opera.JSObject class. |
| Opera 7.50 and earlier allows remote web sites to provide a "Shortcut Icon" (favicon) that is wider than expected, which could allow the web sites to spoof a trusted domain and facilitate phishing attacks using a wide icon and extra spaces. |
| Cross-site scripting (XSS) vulnerability in Opera 6.0 through 7.0 with automatic redirection disabled allows remote attackers to inject arbitrary web script or HTML via the HTTP Location header. |
| Characters from languages are such as Arabic, Hebrew are displayed from RTL (Right To Left) order in Opera 37.0.2192.105088 for Android, due to mishandling of several unicode characters such as U+FE70, U+0622, U+0623 etc and how they are rendered combined with (first strong character) such as an IP address or alphabet could lead to a spoofed URL. It was noticed that by placing neutral characters such as "/", "?" in filepath causes the URL to be flipped and displayed from Right To Left. However, in order for the URL to be spoofed the URL must begin with an IP address followed by neutral characters as omnibox considers IP address to be combination of punctuation and numbers and since LTR (Left To Right) direction is not properly enforced, this causes the entire URL to be treated and rendered from RTL (Right To Left). However, it doesn't have be an IP address, what matters is that first strong character (generally, alphabetic character) in the URL must be an RTL character. |
| Opera Mini 13 and Opera Stable 36 allow remote attackers to spoof the displayed URL via a crafted HTML document, related to the about:blank URL. |
| The Opera Mini application 47.1.2249.129326 for Android allows remote attackers to spoof the Location Permission dialog via a crafted web site. |
| The TLS protocol 1.2 and earlier supports the rsa_fixed_dh, dss_fixed_dh, rsa_fixed_ecdh, and ecdsa_fixed_ecdh values for ClientCertificateType but does not directly document the ability to compute the master secret in certain situations with a client secret key and server public key but not a server secret key, which makes it easier for man-in-the-middle attackers to spoof TLS servers by leveraging knowledge of the secret key for an arbitrary installed client X.509 certificate, aka the "Key Compromise Impersonation (KCI)" issue. |
| The HTTPS protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack. |
| Unspecified vulnerability in Opera Mail before 2016-02-16 on Windows allows user-assisted remote attackers to execute arbitrary code via a crafted e-mail message. |
| The HTTP/2 protocol does not consider the role of the TCP congestion window in providing information about content length, which makes it easier for remote attackers to obtain cleartext data by leveraging a web-browser configuration in which third-party cookies are sent, aka a "HEIST" attack. |
| Opera before 11.00, when Opera Turbo is used, does not properly present information about problematic X.509 certificates on https web sites, which might make it easier for remote attackers to spoof trusted content via a crafted web site. |
| Unspecified vulnerability in the auto-update functionality in Opera before 11.00 allows remote attackers to cause a denial of service (application crash) by triggering an Opera Unite update. |
| Opera before 11.00 on Windows does not properly implement the Insecure Third Party Module warning message, which might make it easier for user-assisted remote attackers to have an unspecified impact via a crafted module. |
| The Cascading Style Sheets (CSS) Extensions for XML implementation in Opera before 11.01 recognizes links to javascript: URLs in the -o-link property, which makes it easier for remote attackers to bypass CSS filtering via a crafted URL. |
| Unspecified vulnerability in Opera before 11.50 has unknown impact and attack vectors, related to a "moderately severe issue." |
| Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via unknown content on a web page, as demonstrated by progorod.ru. |
| The Array.prototype.join method in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via a non-array object that contains initial holes. |
| The SVG implementation in Opera before 11.50 allows remote attackers to cause a denial of service (application crash) via vectors involving a path on which many characters are drawn. |
| Unspecified vulnerability in Opera before 11.50 allows remote attackers to cause a denial of service (memory consumption) via unknown content on a web page, as demonstrated by test262.ecmascript.org. |
