CVE-2009-0915

Vulnerability

Opera versions prior to 9.64 contain an unspecified vulnerability related to plug-ins that allows remote attackers to conduct cross-domain scripting attacks [1][2][3][4]. The exact nature of the bug and the required configuration to reach the affected code path are not disclosed in the available references. Versions affected include those on Linux, Windows, Solaris, and Mac platforms before 9.64 [1][2][3][4].

Exploitation

An attacker can exploit this vulnerability remotely without requiring any special network position or authentication, as the attack vector is over the network via a crafted web page or content that interacts with a vulnerable plug-in. The specific sequence of steps is not detailed in the references, but the attack involves manipulating plug-in behavior to bypass same-origin policies.

Impact

Successful exploitation allows an attacker to perform cross-domain scripting, which can lead to disclosure of sensitive information from other domains, session hijacking, or unauthorized actions on behalf of the victim. The level of compromise depends on the context of the targeted domains and the data accessible there.

Mitigation

Opera 9.64, released on or around March 16, 2009, fixes this issue [1][2][3][4]. Users should upgrade to version 9.64 or later. No workarounds are described in the references. This CVE is not listed on the CISA Known Exploited Vulnerabilities (KEV) catalog as of the publication date.
