Discussion

Opera Web Browser Unspecified Certificate Verification Vulnerability

Opera Web Browser is reported prone to an unspecified certificate verification vulnerability. This issue may allow improper certificates to be used when authenticating connections. An attacker may use forged certificates to carry out various attacks.

It is conjectured that a malicious Web site could take advantage of this by posing as a site that may be trusted. Users may believe a malicious site is trusted as a result. This could lead to the user taking further actions under the assumption the site is trusted, such as authenticating or submitting sensitive or private information.

Further information about this issue and its impacts are not currently available. This BID will be updated as more information becomes available.

Opera versions 7.51 and prior are affected by this issue.
