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. Las URL que usan "javascript:" tienen el protocolo removido cuando se pegaban en la barra de direcciones para proteger a usuarios de ataques de tipo cross-site scripting (XSS), pero en determinadas circunstancias esta eliminación no fue llevada a cabo. Esto podría permitir a usuarios hacer ingeniería social para ejecutar un ataque de tipo XSS contra ellos mismos. • https://security.opera.com/cross-site-scripting-in-ofa-opera-security-advisories • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •

Opera for Android before 54.0.2669.49432 is vulnerable to a sandboxed cross-origin iframe bypass attack. By using a service working inside a sandboxed iframe it is possible to bypass the normal sandboxing attributes. This allows an attacker to make forced redirections without any user interaction from a third-party context. Opera para Android versiones anteriores a 54.0.2669.49432, es vulnerable a un ataque de omisión de iframe de origen cruzado dentro del sandbox. Al utilizar un servicio que funciona dentro de un iframe del sandbox, es posible omitir los atributos normales del sandbox. • https://security.opera.com/bypass-a-restriction-in-ofa-54-opera-security-advisories •
CVSS: 4.3EPSS: 97%CPEs: 42EXPL: 0CVE-2015-4000 – LOGJAM: TLS connections which support export grade DHE key-exchange are vulnerable to MITM attacks
https://notcve.org/view.php?id=CVE-2015-4000
The TLS protocol 1.2 and earlier, when a DHE_EXPORT ciphersuite is enabled on a server but not on a client, does not properly convey a DHE_EXPORT choice, which allows man-in-the-middle attackers to conduct cipher-downgrade attacks by rewriting a ClientHello with DHE replaced by DHE_EXPORT and then rewriting a ServerHello with DHE_EXPORT replaced by DHE, aka the "Logjam" issue. El protocolo TLS 1.2 y anteriores, cuando una suite de cifrado DHE_EXPORT está habilitada en un servidor pero no en un cliente, no transporta una elección DHE_EXPORT, lo que permite a atacantes man-in-the-middle realizar ataques de degradación del cifrado mediante la rescritura de un ClientHello con DHE remplazado por DHE_EXPORT y posteriormente la rescritura de un ServerHello con DHE_EXPORT remplazado por DHE, también conocido como el problema 'Logjam'. A flaw was found in the way the TLS protocol composes the Diffie-Hellman exchange (for both export and non-export grade cipher suites). An attacker could use this flaw to downgrade a DHE connection to use export-grade key sizes, which could then be broken by sufficient pre-computation. This can lead to a passive man-in-the-middle attack in which the attacker is able to decrypt all traffic. • http://aix.software.ibm.com/aix/efixes/security/sendmail_advisory2.asc http://fortiguard.com/advisory/2015-07-09-cve-2015-1793-openssl-alternative-chains-certificate-forgery http://ftp.netbsd.org/pub/NetBSD/security/advisories/NetBSD-SA2015-008.txt.asc http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04876402 http://h20564.www2.hpe.com/hpsc/doc/public/display?docId=emr_na-c04949778 http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10681 http://kb.juniper.net/InfoC • CWE-310: Cryptographic Issues CWE-327: Use of a Broken or Risky Cryptographic Algorithm •
