Opera before 57.0.3098.106 is vulnerable to a DLL Search Order hijacking attack where an attacker can send a ZIP archive composed of an HTML page along with a malicious DLL to the target. Once the document is opened, it may allow the attacker to take full control of the system from any location within the system. The issue lies in the loading of the shcore.dll and dcomp.dll files: these files are being searched for by the program in the same system-wide directory where the HTML file is executed. Opera, en versiones anteriores a la 57.0.3098.106, es vulnerable a un ataque de secuestro de orden de búsqueda de DLL donde un atacante puede enviar un archivo ZIP compuesto por una página HTML junto con un DLL malicioso al objetivo. Una vez se ha abierto el documento, podría permitir que el atacante obtenga el control total del sistema desde cualquier ubicación en éste. • https://blogs.opera.com/desktop/changelog-for-57 https://lucideustech.blogspot.com/2019/02/opera-search-order-hijacking-cve-2018-18913.html • CWE-426: Untrusted Search Path •
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 •
