Is there low hanging fruit for the following observation?

The documentation of the python cgi module is vulnerable to XSS
(cross site scripting)

Re: Microsoft PlayReady security research

Posted by Adam Gowdiak on Mar 21

Hello,

I feel obliged to provide additional comments to this paragraph as I
start to believe that CANAL+ might not deserve sole blame here…

While Microsoft claims there is absolutely no bug at its end, I
personally start to perceive the company as the one that should be
also blamed to some extent.

Below, I am providing you with the reasons that has lead me to such a
conclusion.

For many months, no response from CANAL+ was taken at my end as…

Ping Identity debuts decentralized access management system in early access

Read Time:45 Second

Ping Identity, a Colorado-based IAM software vendor, is making a new product, PingOne Neo, available in a limited early access program. PingOne Neo is designed as a decentralized platform, as opposed to the heavily federated systems commonly in use. It allows for data decentralization, storing credentials and keys on the user’s mobile device, and lets credentials be issued using a wider range of identity proofs, instead of particular government-issued ID.

It works something like a wallet, according to the company. End users request a credential from an issuing organization, which is cryptographically signed and verifiable. That credential becomes a part of the user’s “digital wallet,” and works like a ticket into whatever system or application it is designed to access. PingOne Neo also supports other identity standards that are popular in the market, including OpenID, ISO and W3C.

As critical Microsoft vulnerabilities drop, attackers may adopt new techniques

Read Time:38 Second

While the total number of recorded Microsoft vulnerabilities was higher in 2022 than ever before, the number of critical vulnerabilities declined to its lowest point, according to the latest Microsoft Vulnerability Report by BeyondTrust, released Tuesday.

In 2022, only 6.9% of Microsoft’s vulnerabilities were rated as critical — less than half the number of critical vulnerabilities recorded in 2020. In 2013, 44% of all Microsoft vulnerabilities were classified as critical.

Vulnerabilities categorized as critical are those with characteristics that make their exploitation a potentially high-impact security event.

“This trend indicates that, while overall vulnerabilities have increased in number, the risks and worst-case scenarios associated with these individual vulnerabilities have decreased from previous years,” BeyondTrust said.
