| 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. | |||||
| CVE-2010-2657 | 3 Apple, Microsoft, Opera | 3 Macos, Windows, Opera Browser | 2021-09-08 | 9.3 HIGH | N/A |
| Opera before 10.60 on Windows and Mac OS X does not properly prevent certain double-click operations from running a program located on a web site, which allows user-assisted remote attackers to execute arbitrary code via a crafted web page that bypasses a dialog. | |||||
| CVE-2011-3389 | 4 Google, Microsoft, Mozilla and 1 more | 5 Chrome, Internet Explorer, Windows and 2 more | 2021-07-23 | 4.3 MEDIUM | N/A |
| The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack. | |||||
| CVE-2019-18624 | 1 Opera | 1 Mini | 2021-07-21 | 7.5 HIGH | 9.8 CRITICAL |
| Opera Mini for Android allows attackers to bypass intended restrictions on .apk file download/installation via an RTLO (aka Right to Left Override) approach, as demonstrated by misinterpretation of malicious%E2%80%AEtxt.apk as maliciouskpa.txt. This affects 44.1.2254.142553, 44.1.2254.142659, and 44.1.2254.143214. | |||||
| CVE-2021-23253 | 1 Opera | 1 Opera Mini | 2021-01-20 | 5.0 MEDIUM | 5.3 MEDIUM |
| Opera Mini for Android below 53.1 displays URL left-aligned in the address field. This allows a malicious attacker to craft a URL with a long domain name, e.g. www.safe.opera.com.attacker.com. With the URL being left-aligned, the user will only see the front part (e.g. www.safe.opera.com…) The exact amount depends on the phone screen size but the attacker can craft a number of different domains and target different phones. Starting with version 53.1 Opera Mini displays long URLs with the top-level domain label aligned to the right of the address field which mitigates the issue. | |||||
| CVE-2020-6159 | 1 Opera | 1 Opera | 2020-12-23 | 4.3 MEDIUM | 6.1 MEDIUM |
| URLs using “javascript:” have the protocol removed when pasted into the address bar to protect users from cross-site scripting (XSS) attacks, but in certain circumstances this removal was not performed. This could allow users to be socially engineered to run an XSS attack against themselves. This vulnerability affects Opera for Android versions below 61.0.3076.56532. | |||||
| CVE-2020-6157 | 1 Opera | 1 Opera Touch | 2020-11-30 | 4.3 MEDIUM | 4.3 MEDIUM |
| Opera Touch for iOS before version 2.4.5 is vulnerable to an address bar spoofing attack. The vulnerability allows a malicious page to trick the browser into showing an address of a different page. This may allow the malicious page to impersonate another page and trick a user into providing sensitive data. | |||||
| CVE-2019-12278 | 1 Opera | 1 Opera | 2020-08-24 | 4.3 MEDIUM | 4.3 MEDIUM |
| Opera through 53 on Android allows Address Bar Spoofing. Characters from several languages are displayed in Right-to-Left order, due to mishandling of several Unicode characters.
