The fig of macOS vulnerabilities exploited successful 2023 accrued by much than 30%, according to a caller report. The Software Vulnerability Ratings Report 2024 from spot absorption bundle institution Action1 besides recovered that Microsoft Office programs are becoming much exploitable, portion attackers are targeting load balancers similar NGINX and Citrix astatine a grounds rate.
Action1 analysts utilized information from the National Vulnerability Database and CVEdetails.com to gully 5 insights into however the menace scenery changed from 2022 to 2023. Maintenance of the NVD has slowed importantly since February arsenic the National Institute of Standards and Technology tries to header with a backlog of bundle and hardware flaws being submitted. NIST said the slowdown was the effect of “an summation successful bundle and, therefore, vulnerabilities, arsenic good arsenic a alteration successful interagency support.”
1. macOS and iOS progressively targeted
The study recovered the exploitation rates macOS and iOS experienced accrued by 7% and 8% from 2022 to 2023, suggesting they are being progressively targeted by atrocious actors.
The exploitation complaint is defined arsenic the ratio of exploited vulnerabilities to the full fig of vulnerabilities, and provides a measurement of the software’s susceptibility to exploitation. In contrast, the exploitation rates of Windows desktop operating systems remained unchangeable astatine 4%, showing however Microsoft has a unchangeable vulnerability absorption process.
Despite the full fig of macOS vulnerabilities identified decreasing by 29% successful 2023, 18 exploited vulnerabilities were reported, marking a much than 30% summation from the twelvemonth before.
When it comes to mobile operating systems, the exploitation complaint of 8% for iOS was importantly higher than Android’s 0.2%. This shows that, contempt the information that Android devices had much vulnerabilities reported successful total, menace actors were focusing their efforts connected exploiting iPhones.
iOS besides suffered the highest fig of distant codification exploitation attacks of each mobile operating systems analysed implicit 2021, 2022 and 2023. An exertion with an accrued RCE number whitethorn person much imaginable introduction points for attackers to exploit. The study authors accidental the targeted quality of iPhones is perchance owed to the cognition of the invaluable information they store.
“The summation successful exploited vulnerabilities for MacOS and iOS is simply a concerning inclination for Apple,” the analysts wrote. “For immoderate reason, the institution is not managing to hole vulnerabilities earlier attackers exploit them.
“For organisations, this means they should not lone guarantee regular updates for Apple OS but besides see implementing further information measures for Mac devices.”
2. Load balancers person grounds exploitation rate
Load balancers NGINX and Citrix some had precise precocious exploitation rates successful 2023 — 100% and 57%, respectively. Despite load balancer vulnerabilities making up lone 0.2% of the full fig of vulnerabilities from 2021 to 2023, the exploitation rates are important due to the fact that of the imaginable interaction a palmy exploitation tin have.
Attackers tin summation the quality to intercept, modify and redirect web traffic, thereby accessing delicate information and disrupting services. Compromised load balancers tin besides service arsenic introduction points for launching further attacks wrong the network.
SEE: About 2000 Citrix NetScalers Were Compromised successful Massive Attack Campaigns
For example, the 2023 CitrixBleed zero-day vulnerability allowed attackers to nonstop a ample HTTP GET petition to a NetScaler ADC oregon Citrix Gateway, resulting successful a buffer overflow and the adjacent representation leaking. More than 300 companies were warned astir their vulnerability by the U.S.’s Cybersecurity and Infrastructure Security Agency, and telecommunications institution Xfinity said 36 cardinal customers’ delicate accusation was stolen done CitrixBleed attacks.
The report’s authors wrote: “For organisations, this means they request to wage adjacent attraction to ensuring regular updates for the Citrix load balancer oregon look for alternatives, considering the company’s needs.”
3. Microsoft SQL Server RCE vulnerabilities surge
In 2023, 17 vulnerabilities were identified successful Microsoft SQL Server, marking a 1,600% summation compared to the erstwhile years. Each 1 was an RCE, demonstrating its concerning fig of introduction points. The spike suggests that attackers are getting faster astatine discovering and exploiting chartless RCEs, and that much undiscovered vulnerabilities mightiness stay successful Microsoft SQL.
The report’s authors wrote: “MSSQL is simply a lucrative people for hackers owed to its wide usage successful endeavor environments, lodging invaluable information similar lawsuit accusation and fiscal records. Its distant accessibility makes it susceptible to exploitation from anywhere.
“Consequently, organisations indispensable prioritise robust information measures to safeguard their MSSQL servers and forestall imaginable information breaches.”

4. Microsoft Office targeted owed to likelihood of quality error
Microsoft Office has the highest full fig of vulnerabilities among each bureau apps. Around 80% of its vulnerabilities are deemed captious each year, and betwixt 40 and 50% of them are RCEs. Furthermore, its exploitation complaint accrued by 5% successful 2023.
Attackers presumption bureau apps arsenic much easy exploitable than different bundle due to the fact that they are user-facing and truthful prone to quality error. Common idiosyncratic interactions similar opening documents, enabling macros and clicking connected embedded links tin beryllium utilised arsenic portion of phishing attacks.
SEE: Follina abuses Microsoft Office to execute distant code
Microsoft Office, successful particular, is wide utilized and truthful presents the champion accidental for a palmy onslaught of this nature, arsenic it is recognised and trusted by users. The authors wrote that we tin expect much phishing attacks aimed astatine exploiting MS Office vulnerabilities.
They wrote: “This underscores the request for CISOs to enforce information consciousness among employees and heighten endpoint monitoring with endpoint extortion systems, successful summation to robust patching.”
5. Microsoft Edge experiences spike successful RCEs and vulnerabilities
Edge saw the highest fig of full RCE vulnerabilities among large web browsers successful the past 3 years, with 14. The fig grew by 500% from 2021 to 2022, and past 17% from 2022 to 2023. They accounted for 10% of each reported vulnerabilities, portion conscionable 1% of vulnerabilities successful Chrome and Firefox were RCEs.
SEE: Microsoft Edge cheat sheet
In addition, Edge had a 7% vulnerability exploitation complaint successful 2023 — an summation from 2022’s 5% — portion Chrome and Firefox had astir 2% and 3%, respectively. While Edge really had the lowest fig of reported vulnerabilities of the 3 browsers successful 2022 and 2023, their exploitation is proving the astir lucrative for attackers.
The study authors explained: ”The information that Edge faces an summation successful RCE and exploited vulnerabilities, contempt having a comparatively debased fig of full vulnerabilities, suggests that Microsoft does not yet actively enforce a vulnerability absorption programme for this web browser arsenic rigorously arsenic Google does for Chrome oregon Mozilla does for Firefox.
“This implies that it mightiness not beryllium a bully thought to usage Edge arsenic the main firm web browser.”
