Critical infrastructure gear is full of flaws, but hey, at least it's certified
More than a third could facilitate credential compromise. Another 18 CVEs involved data manipulation, with 13 of these allowing firmware manipulation. And 10 CVEs provided a path to remote code execution.
"Only 51 percent of the examined devices had some sort of authentication for firmware updates, even if it was in the form of hardcoded credentials in some cases," the trio said, adding that 78 percent did not implement cryptographic firmware signing.Most of the software components involved "were written in C++ which is typically more tedious and involved than C or .
The authors note that they followed responsible disclosure practices and that some of the manufacturers disagreed with their findings. In five instances, the authors accepted the vendor's response and dropped or moderated their disclosure, or adjusted the timing of the disclosure. In at least ten cases, no agreement was reached, leading to some public CVEs without vendor participation.
These products are certified but suffer from vulnerabilities that should have been caught in the certification process

Study finds eye color genes are critical for retinal healthMetabolic pathways consist of a series of biochemical reactions in cells that convert a starting component into other products. There is growing evidence that metabolic pathways coupled with external stress factors influence the health of cells and tissues. Many human diseases, including retinal or neurodegenerative diseases, are associated with imbalances in metabolic pathways.

Focused liquid ultrasonography in dropsy protocol for quantitative assessment of subcutaneous edema - Critical CareBackground Although subcutaneous edema is a common symptom of critically ill patients, it is still underreported due to the lack of a systematic method for evaluating it. The present study aims to describe the occurrence and distribution of subcutaneous edema, as well as the risk factors associated with it, in critically ill patients using the focused liquid ultrasonography in dropsy (FLUID) protocol, and to assess their impact on ICU mortality. Methods The FLUID protocol and the pitting test were performed on general ICU patients in China. Cohen’s Kappa coefficient and Bland–Altman plots were used to evaluate the agreement between the two methods at each measurement site and between the whole-body subcutaneous edema scores, respectively, while a repeated measures ANOVA was performed to compare the differences between the two methods in whole-body and body-part measurements. A generalized linear model was used to evaluate the risk factors for subcutaneous edema development and the relationship between subcutaneous edema severity and ICU mortality. Results A total of 145 critically ill patients were evaluated using both approaches, of whom 40 (27.6%) experienced subcutaneous edema. Over 1440 measurements, it was found that ultrasound discovered more subcutaneous edema than the pitting test (ultrasound: 522[36.3%], pitting test: 444[30.8%], χ2 = 9.477, p = 0.002). The FLUID protocol scored edema severity significantly higher than the pitting test in the whole body and specific body parts, including the abdominal wall, thighs, chest wall, and hands. Subcutaneous edema exhibited gravity-dependent distribution patterns, particularly in the abdominal wall. The APACHE II, NT-proBNP, serum creatinine, and sepsis were independent risk factors for subcutaneous edema development. The score of ultrasonic subcutaneous edema was related to ICU mortality. Conclusions The FLUID protocol provides a comprehensive strategy for the semi-quantitative assessment of subcutaneous edema in
