Cisco has warned of a critical security flaw in SPA112 2-Port Phone Adapters that it said could be exploited by a remote attacker to execute arbitrary code on affected devices. The issue, tracked as  CVE-2023-20126 , is rated 9.8 out of a maximum of 10 on the CVSS scoring system. The company credited Catalpa of DBappSecurity for reporting the shortcoming. The  product in question  makes it possible to connect analog phones and fax machines to a VoIP service provider without requiring an upgrade. "This vulnerability is due to a missing authentication process within the firmware upgrade function," the company  said  in a bulletin. "An attacker could exploit this vulnerability by upgrading an affected device to a crafted version of firmware. A successful exploit could allow the attacker to execute arbitrary code on the affected device with full privileges." Despite the severity of the flaw, the networking equipment maker said it does not intend to release fi...

Three new security flaws have been disclosed in Microsoft Azure API Management service that could be abused by malicious actors to gain access to sensitive information or backend services. This includes two server-side request forgery (SSRF) flaws and one instance of unrestricted file upload functionality in the API Management developer portal, according to Israeli cloud security firm Ermetic. "By abusing the SSRF vulnerabilities, attackers could send requests from the service's CORS Proxy and the hosting proxy itself, access internal Azure assets, deny service and bypass web application firewalls," security researcher Liv Matan said in a report shared with The Hacker News. "With the file upload path traversal, attackers could upload malicious files to Azure's hosted internal workload." Azure API Management is a  multicloud management platform  that allows organizations to securely expose their APIs to external and internal customers and enable a wide ...

Cybersecurity researchers have found a way to exploit a recently disclosed critical flaw in PaperCut servers in a manner that bypasses all current detections. Tracked as  CVE-2023-27350  (CVSS score: 9.8), the issue affects PaperCut MF and NG installations that could be exploited by an unauthenticated attacker to execute arbitrary code with SYSTEM privileges. While the flaw was  patched  by the Australian company on March 8, 2023, the first signs of active exploitation emerged on April 13, 2023. Since then, the vulnerability has been  weaponized  by multiple threat groups, including  ransomware actors , with post-exploitation activity resulting in the execution of PowerShell commands designed to drop additional payloads. Now, VulnCheck has  published  a proof-of-concept (PoC) exploit that sidesteps existing detection signatures by leveraging the fact that "PaperCut NG and MF offer multiple paths to code execution." It's worth noting th...

IT and cybersecurity teams are so inundated with security notifications and alerts within their own systems, it’s difficult to monitor external malicious environments – which only makes them that much more threatening.  In March, a high-profile data breach hit national headlines when personally identifiable information connected to hundreds of lawmakers and staff was leaked on the dark web. The cybersecurity incident involved the DC Health Link, an online marketplace that administers health plans for members of Congress and Capitol Hill staff. According to news reports, the FBI had successfully purchased a portion of the data – which included social security numbers and other sensitive information – on the dark web.  Because of the prominence of the victims, the story was picked up by a slew of media outlets that rarely cover dark web-related cybersecurity crimes. The story not only shed light on one of the most dangerous aspects of the internet, it reminded us that the dar...

Three different threat actors leveraged hundreds of elaborate fictitious personas on Facebook and Instagram to target individuals located in South Asia as part of disparate attacks. "Each of these APTs relied heavily on social engineering to trick people into clicking on malicious links, downloading malware or sharing personal information across the internet," Guy Rosen, chief information security officer at Meta,  said . "This investment in social engineering meant that these threat actors did not have to invest as much on the malware side." The fake accounts, in addition to using traditional lures like women looking for a romantic connection, masqueraded as recruiters, journalists, or military personnel. At least two of the  cyber espionage efforts  entailed the use of low-sophistication malware with reduced capabilities, likely in an attempt to get past  app verification checks  established by Apple and Google.  One of the groups that came under Met...

Meta said it took steps to take down more than 1,000 malicious URLs from being shared across its services that were found to leverage OpenAI's ChatGPT as a lure to propagate about 10 malware families since March 2023. The development comes  against  the backdrop of  fake ChatGPT   web browser extensions  being increasingly used to steal users' Facebook account credentials with an aim to run unauthorized ads from hijacked business accounts. "Threat actors create malicious browser extensions available in official web stores that claim to offer ChatGPT-based tools," Meta  said . "They would then promote these malicious extensions on social media and through sponsored search results to trick people into downloading malware." The social media giant said it has blocked several iterations of a multi-pronged malware campaign dubbed  Ducktail  over the years, adding it issued a cease and desist letter to individuals behind the operation who are locate...
