Virtualization services supplier VMware has alerted consumers to the existence of a proof-of-strategy (PoC) exploit for a a short while ago patched security flaw in Aria Operations for Logs.
Tracked as CVE-2023-34051 (CVSS score: 8.1), the superior-severity vulnerability relates to a scenario of authentication bypass that could lead to distant code execution.
“An unauthenticated, malicious actor can inject data files into the functioning process of an impacted equipment which can end result in remote code execution,” VMware famous in an advisory on October 19, 2023.
James Horseman from Horizon3.ai and the Randori Attack Team have been credited with discovering and reporting the flaw.
Horizon3.ai has since manufactured readily available a PoC for the vulnerability, prompting VMware to revise its advisory this 7 days.
It can be well worth noting that CVE-2023-34051 is a patch bypass for a established of critical flaws that have been addressed by VMware previously this January that could expose end users to remote code execution assaults.
“This patch bypass would not be extremely complicated for an attacker to discover,” Horseman explained. “This attack highlights the worth of protection in depth. A defender are not able to usually rely on that an formal patch absolutely mitigates a vulnerability.”
The disclosure arrives as Citrix unveiled an advisory of its possess, urging buyers to implement fixes for CVE-2023-4966 (CVSS score: 9.4), a critical security vulnerability affecting NetScaler ADC and NetScaler Gateway that has come under lively exploitation in the wild.
“We now have experiences of incidents regular with session hijacking, and have gained credible reviews of qualified assaults exploiting this vulnerability,” the firm claimed this 7 days, corroborating a report from Google-owned Mandiant.
The exploitation efforts are also probable to ramp up in the coming times provided the availability of a PoC exploit, dubbed Citrix Bleed.
“Below we saw an exciting case in point of a vulnerability triggered by not thoroughly knowledge snprintf,” Assetnote researcher Dylan Pindur said.
“Even while snprintf is proposed as the protected edition of sprintf it is continue to significant to be mindful. A buffer overflow was prevented by utilizing snprintf but the subsequent buffer over-study was even now an issue.”
The active exploitation of CVE-2023-4966 has prompted the U.S. Cybersecurity and Infrastructure Security Agency (CISA) to incorporate it to the Recognised Exploited Vulnerabilities (KEV) catalog, requiring federal organizations in the U.S. to implement the latest patches by November 8, 2023.
The most current developments also follow the release of updates for three critical distant code execution vulnerabilities in SolarWinds Accessibility Rights Supervisor (CVE-2023-35182, CVE-2023-35185, and CVE-2023-35187, CVSS scores: 9.8) that remote attackers could use to operate code with System privileges.
